I've mostly been puttering around on backroads, and the stock bike, with free airbox and muffler mods, was happiest around 52 mph. It would go faster, but just didn't feel best. With the 14t, it wants to run 65 actual mph, and is smoother than it had been! I know that doesn't compute, I was turning 5500 vs 6400 now. I think the engine is happy to be loaded more - maybe a FI thing... Coming off a 4-way stop, and turning used to be awkward. 1st was too low, I had to be careful with the throttle, and I had to shift mid-corner. Now I just take off like I have on all my previous bikes, and can shift to second after I've straightened up. For the first time, I had absolutely NO numbness in my hands.

Top speed remains at 84 mph (well-it was windy today, so maybe the bike is a bit faster!). In 5th, the bike pulled up a medium-slope hill at 77 mph with a 10 mph headwind. (WeatherUnderground's local weatherstations are great for finding out stuff like this).

Anyhow, I much recommend gearing UP for those o you who road ride alot.

Hi all, I've just completed a 700k all highway ride with the new 14t c/s and some of you may be interested in my findings.

My WR has the 290 BB kit, power pipe, Yammy racing exhaust, a small windscreen and new Bridgestone TW rear tyre.
Me and bag weigh in at approx 90kg (around 185 pounds).

Bike cruised nicely at 110kph (68mph), can sit on 120kph (75mph) and accelerate even then if necessary (a little) but a headwind will slow her down a noticeably. My bike appears to have a sweet-spot at 105kph. No vibrations anywhere in the speed range and comfortable with the Sweetcheeks seat cover and screen, no fatigue at all.

Fuel consumption was 4 litres per 100ks which is about 53 mpg (US gallons). That's all highway riding at the above speeds. Range was 174 klm (44 k with the LowFuel light on) and 6.88 litres to fill her again.

As an aside, the speedo is now spot-on accurate with the GPS speed indicator, right through the speed range.

She can still carry a pillion passenger, one chunky chick, no worries but wheelies are a little harder.

So my experience with the 14t sprocket is all positive, allbeit, highway use, which is 90% of my thing. More than anything she seems to rev a fair bit lower. I love this little girl even more now. Regards John.

With my WR250R converted to Supermoto I have been using 14/42 (stock WRX: 13/42) for more than 10.000kms.
For commuting this is perfect. Lower engine revs, lower fuel consumption (3,5l/100km with my 130km/day backroad slope) and always relaxed riding at >100km/h.

However, when doing small winding roads in the mountains at 1500m of altitude up to 2500m (for the tour linked) it will not work out.
I regret not having used the stock 13 teeth sprocket. At greater altitude the WR becomes really weak at low rev. When going uphill as fast as possible through extremely tight bends and slow bigbikes, everytime you change gears you will get stuck at low rev . That is some kind of nasty for this sort of riding. Maybe not "unrideable" but rather near to it. Next time for these rides I will gear down to stock.
Greets, Phil

Thank you WRR riders for this thread. I read a good deal of it before deciding to buy one earlier this summer. There is lots of good info here.

4,500 miles so far this year on the WR and loving it, what a great bike.

Thanks again!

I had to put a new main switch(ignition) on my bike and like a dummy, I did not take pics.

I was wondering if someone has some pics or would take some with the headlight and shroud removed.

I also seem to have lost, or can't remember what the right side wire guide looks like or what it connects to.

Thanks for any help.

Well I finally had the chance to ride my '11 WR250x and my '09 KLX351 back to back yesterday. Here is my take:

The fit and finish on the WR seems superior to the KLX and it looks more modern. The KLX felt like a moped when it was new and was still a 250. The WR feels less moped-like in stock form. I noticed right away that if you shift down and rev up the WR, it actually pulls pretty good at higher RPM's. But my KLX (now with 351) pulls harder and has better throttle response than the WR. It has more torque, and you can tell. But once up to highway speeds the WR rides better. This may be partly due to the smooth tires vs. knobbies, but I think there's a difference in gearing. 6th gear on the WR feel almost like overdrive, where the KLX makes me wish for another gear. Both of my bikes are running stock gearing right now. I'm guessing top speed will be higher on the WR. Neither bike has much vibration in the bars, but the KLX has more vibration felt through the tank, seat, and footpegs...not terrible, but much more than the WR. For off-road riding, the KLX better suits my riding style. It has better low end grunt and is more luggable than the WR. The power delivery at slow speeds is also better. I think the off-idle slow speed fuel injection stumble on the WR might be a challenge for me off-road...I'm a slow rider though. A throttle tamer might help.

My original plan was to try to get down to one "do it all" bike...the WR. I was going to get a set of R wheels/tires and have the best of both worlds. But the more I thought about it, the less convinced I was. I'm short (5' 4") and to run R wheels I would need to lower the bike and cut the seat to get one foot down. But then I wouldn't really want it lower when running in X mode. And the kickstand would probably be too long in X mode if the bike were lowered. So to be totally happy when converting from X to R, I would have to swap wheels, install or remove lowering link, adjust fork height, change from low seat to tall seat, maybe change out the chain depending on sprocket selection, and possibly swap kickstands. This just seems like too much trouble, so I've decided that I will keep the KLX and use it as my 90% dirt/10% street bike and use the WR for adventure travel and 90% street/10% dirt.

Here are pics of both bikes for comparison:

I see the bike above has the front dropped a bit, did you lower the rear also?

[japako]

Nice Rumble,, thanks for the great pics. That really will help me put it back together. I owe ya one..

[byron555]

How great these things are! I put them on yesterday, wire through a relay to the ignition switch and battery. I also added (finally) a GPS plug. Hands stayed toasty on the interstate at 70mph. Tusk brand, and only cost $20

Correct.

I bought 17 inch rims for my WRR from Warp 9. They came with a stock brake rotor on the front. I want to put a bigger brake on the front but warp 9 is telling me no one makes a relocator bracket for the caliper. Does anyone know where I can get one?

[Sewerat]

Any good local machinist?

[Mike_drz]

the chinese also pretty good as uk

Well, mine was tailormade. That could be done for your caliper easily. However, what is your location?
