Wr250r Top Speed??

With stock gearing mine hit 80 mph in 4th gear (per my Garmin 2730 GPS) and it hadn't hit the rev limiter. The bike is bone stock too.

Anybody topped 100 mph (verified by gps of course)?

Not sayin' I got beat, but I was passed by a wr250x while I was travelling at 102MPH (108 indicated.) He didn't fly by me, but he was definately going faster than 102mph.

I'm currently running 13/45 sprockets, but I believe you've convinced me to drop the gearing just a tad further next time around. Thanks

I'm more interested to know how the top speed compares to other bikes. But anything over 100mph is just bullshit, just won't happen unless in freefall or some other freaky conditions.

and thats on what looks like an 80cc moped. , I'm not saying that 100mph + is easy or normal for the WR , but its certainly not impossible.

The question that needs to be asked isn't top speed, but an effortless maximum velocity. In that case my WRR will do 95-100km/h for hours on end with 13/48 and a d606. Stock it'll do 110 easily, maybe even 115.

The fasted i've been on the wrr is 135 stock and 140 with gearing and 606. this is GPS verified.

"with gearing" .... ?

140 kph is 87 mph

So far we have one claim of 102mph 'actual'

... I am just curious if the WRR's stock gearing ... is a little too short to let it reach a higher maximum ?

For reference ... a stock engined 250 2 stroke MX bike will do right around 100 ... (obviously geared taller than stock) ... thats with their typical 45rwhp

... as I remember ... a Ninja 250 will do 99 or 100 ?

I was guessing a WRR would do 'bout 95.

Interesting thread.

Many other threads discussing the WR250R power. Here's one:

bike --- hp --- torque ---weight ----- qtr-mile
DRZ--- 32.5 --- 23.9 --- 335 lbs --- 14.30 @ 87.81
WR --- 23.5 ---14.4 --- 301 lbs --- 15.51 @ 80.88

If it does quarter mile at elapsed speed of 80.88. It could conceivably top out at around 85 to 90. Aerodynamics and horsepower play a big part as speeds get higher but the WRR top speed will be limited due to 23.5 hp.

Are you insisting that it would not be possible under any circumstances? Hell, there are verified records of 50cc bikes going over 130MPH! http://www.scta-bni.org/Bonneville/BNI_records.htm

Again, I was not the one riding the wr250X (supermoto) so I don't need to defend what it can or can't do, I am simply stating what I know to be FACT as verified by my gps as I was passed. Bike could have had a big block chevy or a flux capacitor in it for all I know (but I'm pretty sure those are only good for 88mph anyway), but it was definately a wr250x traveling at least 102.1mph

What I wanna know is, why would you want to.

It's funny, one of my rides for example is an RXV-550. And just about every 12 year old kid who asks me about the bike, the first thing they wanna know is "How fast does it go?". They are really disappointed when I tell them I don't know, I've never tried to go that fast on it.

Mine is geared a bit stiffer for dirt road ripping rather than enduro riding, and I could easily estimate what the top speed would be since it feels like it would run out of revs first, but really. WHY would I ride that bike that fast, it wouldn't be a comfortable ride.

My V-Strom was no big deal to hit triple digits, any street-type bike sure, but a dirt-style 250, I don't see the point.

General rule of thumb for non-streamlined street-legal bikes is that it takes 40+ RWHP to do a true 100. With typical frontal areas and coefficients of drag, this is simply the physics of the situation.
