Today I got a read on fuel economy for the Typhoon 125. Not really good I am afraid at 60 MPG.

Its possible the dealer fill was not actually completely full and that is why its so low. It looked full but during my fill up it kept the same level in the tank for at least another 1/4 of a gallon before it finely went to the bottom of the filler neck. Also in every bike I have ever owned the first tank is usually not the best and things can improve dramatically.

Hopefully this is the case but I am not really sure. Its air cooled and carbureted for starters and it seems to be high strong with a resident rpm that is perhaps a 2,000 or more rpm's higher then many other scoots out there. Last but not least the scooter is just so fun to ride you end up pushing it harder then normal.

Still 60 MPG is pretty bad for a 125 so I expect it to improve perhaps dramatically over the next few tanks. It probably did not help it was a dog the first 40 miles as well.

I hope tomorrow I will have time to fill up the SportCity 125 and see how it compares. However its looking like its perhaps slightly worse. Of coarse again it was a dog when brand spanking new and I don't think it was completely full.

Also hope to fill up the Agility 125. I can tell you this scooter appears to be doing very well economy wise. I have traveled 133 km and its slightly below a half tank on the gauge. I know the last half goes fast but its only a 1.3 gallon tank I believe.

Today I did run the SportCity 125. Its really looking like I will have to take into the shop for some carb adjustments. The bloody thing died on me at a traffic light and would not restart. This happened at the intersection by Barnes and Noble in Lynnwood. I had to push it off the street and after 4 or 5 attempts to get it started it would not fire and stay running. So I parked it and went in and read some books and tried again 30 minutes later and it fired right up and ran fine the rest of the day. So go figure!

When I got back home I was at 70 miles on the clock so I dumped the factory fill. It was dark in color and had some glitter when draining the filter but otherwise looked fine. Tomorrow or Sunday I will do the final drive and be done with that stuff on all the new bikes. Next service will be the dealers 600 mile service however on the 125's they don't get a valve adjustment so I may just change the oil myself. All the dealers do is change the oil and charge you a fortune for it. If the valves need to be checked I will have them do it.

Fueled up the Agility 125 and the SportCity 125 today. For the SportCity 125 I got a measly 57 MPG. For the record though I don't think the selling dealer topped it off. The gas gauge was on full for a little while but seemed to move down faster then the Typhoon. As I already said I expect both the SportCity 125 and the Typhoon 125 to improve. The question is by how much?

For the Agility 125 I did a lot better. Managed to pull off 90 MPG on the dealer fill and this included some mild wrenching and some break in procedures. I expect it to also improve as it gets some miles on it as long as I stay off the throttle of coarse. I am not expecting a major improvement because it turned out so well already but maybe 92 to 95 MPG is doable. Not bad for an air cooled and carbureted old school engine. So much for technology improving things!

BTW, you gotta watch the gas gauge on the Agility. I left home this morning at about a 1/4 tank of gas just into the white zone on the gauge. I traveled 8 miles on an errand and it went from 1/4 tank down into the red. I thought for sure I can make it another 10 miles to the Woodinville Costco for one of them $1.50 Hot Dog's and some fuel but I made it only about 6 miles to Bothell. In that short period of time the gauge was pegged deep into the red empty zone. I noticed the engine started to miss a bit and at that point I decided to turn off and get some fuel at the Chevron in Bothell. When I popped the gas cap off the tank was completely empty. Only the bottom of the tank was wet. I am pretty sure I was running on what was left in the float bowl. Could I have made it to Woodinville. Perhaps on a wing and a prayer but I think the traffic in downtown Woodinville would have done me in. At least I would have several gas stations I could easily push it to.

Anyways lesson learned on the Agility is its smart to get fuel as soon as the gauge reaches the red zone. If I had one complaint about the Agility a slightly larger tank would be nice but if I wanted to carry extra fuel I do have an MSR Fuel Bottle available for those purposes. Maybe next time I will actually see how far it will go compared to when I chickened out today.

The Motorcycle.com review of the Typhoon stated poor mileage as well.

Yeah I read that as well so the low economy figures are not surprising. My theory is the engine seems tuned to be high strung so it seems like it turns over at a much higher RPM then the Zuma 125, PCX 125 or Agility 125. In fact it seems the motor spends 80% of the time at near maximum speed and its the CVT doing all the work. I don't notice a great deal of difference in how fast the motor is running regardless of speed. Because of this it burns a surprising amount of fuel.

I still expect things to improve but I bet if I can reach 70 MPG that will be about as good as it gets. This is really no better then most 250cc to 300cc scooters but obviously still way better then just about any car.

If Piaggio really wanted to improve fuel economy the first thing they would do is tune the motor for more low end torque so it does not have to spin so fast. 2nd thing they can do is add 2 more valves or at least 1 more like the new Piaggio 3V engine. Last but not least they can add fuel injection and at this point it will probably be at least the mid 80's MPG wise. However all this stuff cost money to engineer and the Typhoon does come in at a certain price point and the current engine is very proven. Supposedly the Leader engines are very solid design. Sometimes if its not broken don't fix it.

Even my made in Taiwan SYM HD 200 EVO has four valves so you wouldn't expect Piaggio to be behind the curve.

Regarding high rpm's, is there a possibility there's a malfunction of some sort in the drivetrain causing slippage? You said the motor sounds about the same regardless of the speed and that got me to wondering.

Unless they're all like that. In which case you wonder about the wisdom of owning one.

The Piaggio group has upped the anti on its 50cc engines as most if not all of them are 4 valves now. However they have not done much to the larger motors (Yet). A few water cooled versions and the new 3V 150cc engine is about the most they have done for a while now.

I kind of doubt anything is really wrong with the drivetrain. I think its just how Piaggio designed it. The behavior actually seems fairly typical with CVT scooters or anything with a CVT transmission. The engine will run in its sweet spot pretty continuously and its the CVT transmission that does all the work. You do notice slightly higher rpm's when WOT at or near maximum speed and rpm's do decrease at slower speeds and as you stop. However in the 30-50 MPH range it seems the motor is running a pretty steady speed plus or minus 500 or so RPM's. I also notice the exact same behavior on the SportCity 125. Same Leader engine and drivetrain.

In Hawaii a few years ago I had a Dodge Caliber with a CVT transmission and it ran just like a scooter. Actually drove me nuts but I did get used to it. The engine spent most of the time at about 3,200 rpm's give or take a few hundred and you never felt it shift.

Some scooters seem to have more variance and use the motor a little more. My PCX and Elite 110 do. I am pretty sure my SH150i does as well. Come to think of it so does the Silverwing. However my Reflex and my Majesty run pretty much the same as the Piaggio's do. Its just however its designed to run.

The scooter market is really heating up especially in Europe. A lot of advanced tech in the latest models that really help squeeze every ounce of efficiency out of them. I think Piaggio will have to up the anti to remain competitive and I bet they will. They have a lot of solid stuff right now that is proven but definitely not the most efficient out there.

Thank you for all the information. You certainly know much more about various scooters, some of which I never heard of before joining this forum, plus I just bought my first scooter in ages last March. I think I need to go up to Tucson and take some test rides on a variety of scooters in order to have some standards of comparison.

Does Piaggio own Vespa and do they now also own Ducati?

You could put some heavier sliders or rollers in to tone down the revs some. Once the belt breaks in it should be less frenetic.

You need to put a few hundred miles on before doing a proper write up on efficiency.

I believe Piaggio owns Vespa, Aprilia, MV Augusta, and Moto Guzzi.

Exactly this is why I am thinking the economy will improve plus its impossible to say just how full the dealer got it. Every machine I have ever owned that first tank kind of sucked because everything is brand new and stiff.

I did not think about changing the sliders but this could help a bit. It just depends on what the actual torque curve is. For maximum reliability I usually don't mess with things much anymore but rollers are pretty benign and safe to do. I will have to research and see what mods are available. I am sure they have different weight sliders or rollers available. This particular engine is used in dozens of scooter models from the Piaggio Group.

Not sure why most of the dealers do it this way. It seems counter productive and more costly to the consumer and the dealer. Its like most dealers refuse to use its own shop for uncrating and assembly. I am guessing the warehouse down south charges less for the same work the shop at the dealer charges the sales department for. Still kind of silly because they tell me they still have to go through them to make sure they did everything right. If I owned a dealer at that point I would just say "heck with it we will do the assembly as well". I am sure this would be obvious an a cost analysis but it highlights just how most dealers are run! Being mom and pop operations they will go with what is easier and not exactly what is cheaper. .
A warehouse and setup company is usually a lot cheaper than for a dealer to warehouse and setup his own units. The guy setting them up makes a lot less than the Technicians in the shop, they do it faster, and uncrating and assembling bikes is not a very difficult job. Also, most dealers don't have a warehouse to inventory all their bikes, nor floor space to put everything on it they ordered, because many companies require them to order a year's worth of bikes at a time, and they receive massive shipments of bikes all at once. A dealer that sells 1200 bikes a year might have 600 in inventory and space on his floor for 50 or so. They need a forklift to unload them, and a place to warehouse them until they set them up for the floor. In addition, it is easier to do dealer trades with other dealers if everyone has their stuff in a central location and you can check what other dealers have still in the crate instead of on the floor and perhaps banged up. What the dealer's shop does is called the Pre-Delivery inspection, and this is different than the set-up. It does require a higher level skill set than uncrating bikes and putting them together. Also, most dealers aren't set up to handle disposing of the crates the bikes come in.

You do know you can get a 200cc big bore kit for that typhoon, I hope.

I believe that is for the 2 stroke.(the 189 or 192cc kit)

I think the reason for the high strung nature of your Typhoon that you mention is due to it's really short stroke.

If the specs are to be trusted, the Piaggio website claims that the Typhoon has a 2.2 inch bore with 1.1 inch stroke. The short stroke would mean that the engine spins really high and the Horsepower is made really high up in the RPM range although Midrange torque on these types of motors are usually really low. You really have to keep short stroke motors up in the high RPM range to get any power out of them.

Your Fly 150 on the other hand has a bore of 2.28 inches and a stroke of 2.3 inch which would make it a square engine. These types of engines give you a balance of mid range torque and relatively good power in the upper RPM range but don't spin as high as short stroke motor would and not as exciting to ride.

The Agility has a 52.4 mm bore with a 57.8 mm stroke. Long stroke motors typically make their power down low but since this motor is really small to begin with, I think it still spins as high as your Fly 150 does.

Judging by your review of all your scooters, I think its safe to assume that the engine types I described fit your scooter's profiles.

Finely was able to pull out the Typhoon 125 and SportCity 125 for a quick run. It had been a month since either one had been ran. First I took a 3 week vacation to Europe then came home to some serious weather that grounded even the most seasoned riders. Finely got a break this afternoon and was able to run them up. My primary concern was the carbs running dry and being a PITA to start. I am using a bit of TCW3 oil and a high quality stabilizer so I am not concerned about gumming up the carbs just drying out and being a pain to start. Some bikes can sit a long time and fire right up but others its like waking the dead. I am happy to report both scooters fired up on first crank and despite the ambient temperature being in the mid 50's they actually ran really good out of the gate with little warm up time. It seems the jetting may in fact be set up for cooler riding and not warmer riding. Even the SportCity 125 ran without drama out of the gate and its the picky one.

Hopefully our break in the weather holds so I can run the Agility 125 tonight. Not sure if its going to be drama free or not. I also hope we get more breaks in the weather this fall and winter and I can ride as much as possible. The cost savings is pretty huge. Since getting back I have filled up both my cars and already burned through most of that gas. It cost over $100 just to keep the cars going. For some stuff I need the cars but for 80% of what I do any bike will do and the more economical the bike the more $$ in my pocket. During May-Aug I was spending about $20 per month on fuel and now all of a sudden I am spending $400 average on fuel if the weather does not break.

As it looks right now we are quickly heading for another deluge!

Took the Typhoon out and ran over to the selling dealer to inquire about the broken horn that is to be replaced under warranty? The new horn did in fact come in and they tried contacting me a few times but I was in Europe so I never got the calls or messages. Being October they were not really busy and they just went ahead and replaced the horn today. Kudos to Lynnwood Vespa/Triumph for the fast service. New horn works great and sadly needed!

While waiting I took out a Factory Demo Triumph Tiger 800. It is a really nice bike but a bit out of reach. My trades did not help much in the equation. Was not really serious at this time anyway. I am looking to reduce the fleet but kind of waiting for just the right bike to come along.
