Old style maybe ,but I still put a lot of miles on the GZ,as you on your DR 200. I overlook the bikes limits and enjoy the ride. I value your opinion. I hope to see one at the upcoming bike show.

The GW is completely different from a GZ. The seating position of the GW is more of a standard configuration, while the GZ is feet-forward cruiser-style. The motors are completely different...GW is a fuel-injected liquid-cooled parallel twin, and the GZ is a carbureted air-cooled single.

The GW has a bigger frame and doesn't feel small like a GZ does. I didn't like the seat on the GW, though...I could tell it would be cramped with my riding suit on. I'm back to looking at the TU250...I may buy one next spring.

There is also the power curve, peak power vs broad power output, and the TU is very odd in that it has a lot of power (for a 250) starting at 4000 rpm building slowly to about 7600 rpm where it flattens out to the 8500 red line.
What that means in the real world is good speed on the road wiithout high rpm's.
Its also one engine you can do whatever you want with, without any concern about the engine.
The engine runs smooth and cool, so you can scream the thing across the US and back without worry or discomfort.
And even running at a low (for a 250) 5000 rpm you have no problems doing a real 70+ mph.
Even running at 85 and 7500 rpm is nice and the bike feels like it will do it all day for months.
Unlike some bikes, the TU seems to love heat, the hotter it is out, the better the motor seems to run.

Its NOT a dual sport though, and it sucks in the rough dirt, the forks and 18 inch front wheel do not like rough stuff at all, plus, the way the engine is made to get a lot of mid range power makes it impossible to get much if any more power out of the bike. Airbox and exhaust mods seem to do nothing, but the FI system works very well, not feeling lean even if you do mods.
For any off road use, its very risky, the brake and shifter stick WAY out past the motor, the gas tank is wider and tends to get dents, the headlight would break, levers snap off, etc.
That big headlight is the best I ever had on any bike for night riding though.
That is a shame, as the motor is great in the dirt, nice power curve, and the bike is fairly light.

When I had my xt250, I do not think I could get the bike much over 70 mph under most situations, and it did not like real high rpm's a lot. It did not seem happy at higher speeds, but was one tough bike in the dirt.

The XT250 motor sort of reminded me of the TW 200 motor, as not liking high rpms for long.
Brett: With a Feet per minute, (NOT rpm) calculation of the TW engine,I think you may be mistaken on the not liking the high rpm thing. I could be mistaking what your saying however?. I'll try and find the FPM calc..

I've put 8500 miles on an XT250 in the past two summers. Some of that was highway cruising unfortunately. Thought I'd chime in about what it is and is not capable of on the highway.

Flat ground cruising along with no head wind I put the speedo between 65-70 and go for hours. The speedo is off 10% so that's an actual speed of 60 or a little more. Fine for deserted 2-lane blacktops. If there is any traffic you'll be getting passed or pulling off and looking at your map for an alternate. I plan my trips for dirt roads and smaller highways that I know don't have traffic.

On the mountain passes, or with a headwind, I downshift to 4th and put the speedo on 55, which is 50 actual. I've ridden like that for hours and the motor seems to just purr along, altho it will use some oil doing that. Not sure what the revs are in that situation but it's surely more than cruising in 5th gear at 60mph. In 4th gear I have looked down and found myself over 60 so it's not at redline yet. I would guess 7k.

I can't get it over about 75 indicated on flat ground. On a downhill I can get it to about 82-83 indicated. Most of the time I'm cruising forest roads in 3rd or 4th gear so it works for me just fine.

This is all with about 200 lbs of rider/gear and 50 lbs strapped on the back. Most of my riding is at high elev so I'm down on power a little.

It's a fun bike but not for people who are in a hurry. -al

Excellent pictures! I'd love to see that klx250 on a trip to Prudhoe Bay. I rode to Prudhoe bay this past summer on my F800GS. If I would of had the time I would of taken my klr250. Its great seeing little bikes on long trips. How did the klx250 do at altitude? Any starting or running issues?

Not sure why, but the TU with the same power, or less, will do 85 mph (actual) on the interstate in traffic.
I have done 50 miles at a time at that speed quite a few times.
The cars set up a big draft which pulls me along, and maybe tires come into play, you have to loose some speed with dual sport tires.
No traffic, no wind, 80 mph is likely tops, but the motor and the bike is very happy there, no oil use, no noise, low oil temps.
So the XT and TU sound close, with the TU having street tires, being lower (less wind drag?).


As far as the TW200 goes, it made noises at higher rpm's letting me know it was not happy.
It does not hold much oil, runs hot (not a plated bore), and an aftermarket oil cooler is a popular mod for people that run them hard.
Short bursts were fine, say in the dirt, but on the street I would get what sounded like ignition knock, and I had increased the main jet a step and shimmed the needle.

Thanks guys, it was a dream trip.

I switched the main from 120 to 115 and dropped the needle a notch. Even so, it got breathless/powerless at 12,500', but so did I. Always started easily though.

I think less drag is an important consideration. And I think it explains why my CBR250R that has 5 less rear-wheel hp and 67 lbs more weight - has about a 3 mph higher top speed than my WR250R. 93 mph vs. 90 mph.

Maybe it's tires. Or like I said I ride at higher elevs, mostly over 5k, so that might slow me down more than I realize. I was as low as 1000ft one time last summer and it didn't really feel much different, but I'm jetted down a little so I was a little lean then. Yamaha lists the top speed as 73mph though. I always have full saddlebags too which create a lot of drag. When you are at the limit of the bike that makes a difference.

Last summer I started experimenting with opening the air box a little. It made a big difference while riding around in the woods. But I never got out on the highway. It wouldn't surprise me if I can get another 5mph. That air box is extremely restrictive. Al

I live and ride at 5000+ft myself......you take a BIG hp loss at our elevations. The less hp you have to begin with tho, the less you notice the loss from my experience. You lose aproximately 3% of your hp for every 1000ft up you go.....15% of 20hp would be a 3hp loss.....not as noticeable as losing 15% of 170hp, which is 26hp or so. Believe me that you FEEL!

And as far as opening the airbox....if you open it enough it'll make a big difference in throttle response and power, I highly recommend it. You WILL need to jet up accordingly tho. And if you combine opening up the airbox with some well placed cut-outs, and adding a freer flowing exhaust, you'll really feel a difference Best mods I've done to my dirt bikes/dualsports

Back in the mid 80's I bagged a bunch of passes....very slowly, on my 100% stock Honda XR185. When I went back the next year, I had the same XR, but bored to 205cc, with a big fin Honda ATV cylinder, with 12.5:1 compression ratio and a super trapp exhaust system. It was much nicer, more power, and was very happy with 1/2 and 1/2 regular + premium. At altitude, you need to bump up compression, and lean out the carb. Other great thing about this bike that they ruined the next year, was that from first gear to 6th was a huge spread in ratios. It would creep along at super slow trials speeds over basketball size boulders, but would tolerate 55 mph when necessary....and it weighed 202 pounds

I actually think it's the other way around. If you lose 20% off of 16hp you barely have enough to get out of your own way. If you lose 20% from 100hp you still have 80 which is plenty.

The problem I have is that I am up and down so much in a single ride. In a single trip I can be in 10k ft mtns and down to the desert at 4k. What I was doing end of last season was running a #30 main jet (2 sizes down from the stock 35) which feels about right at southern desert elevations with the airbox closed up, then opening the airbox when in the mountains. It's relatively easy to open/close, giving me two different intake settings. If I wanted to open the airbox and tune for highway performance, I would have to jet up and then I'd have a dog in the mountains. So I just avoid highways where 60mph isn't fast enough. That's half the fun of touring on a little bike anyway, going out of your way to stay off the beaten path. I didn't buy this bike for the highway. -al
