Yamaha WR250R Mega Thread

[Wade]

This bike is turning into an ultra lite adventure bike...

Highpayload ability (for a dirt bike), reportedly good street ability, great off road ability, high output alternator for farkles, a sorta comfortable seat...

I wanna know more...

How are the vibes on the road?

1. When will an aftermarket tank come to market... 2 gallons just ain't enough.
2. Can you put the bike in a mode that will allow for lower octane fuel that you might have to use? I know other bikes can do this.

Vibes? What vibes? Seriously, the balancer seems to do a very good job of keeping vibes down, and since the motor is just putting along in 6th at 65mph (there's no tach, but I thought I saw a post where the computed engine RPM based on stock gear ratios was in the 4k-5k range), it's not working too hard at "legal" speeds.

I'd argue the seat thing though. While I agree it's wayyyy softer than my stock KTM seat was, it's still no pillow to sit on. Put it this way, I'm glad it's a 2 gal tank, because I can't imagine putting 200+ miles on this bike with the stock seat without getting off to stretch. If I were going to put some big miles on her, I'd be looking for an aftermarket seat or a cover of some kind (Airhawk, sheepskin, Airhawk + sheepskin.... ).

I think the jury's verdict is the WRR is an open loop EFI, and there's no knock sensor, so while running lower octane fuel is theoretically possible, I wouldn't want to stress the motor too much because there's nothing in the loop to prevent pinging (i.e. no automated way to retard ignition timing, etc., to compensate).

Has anyone tried lower octane fuel in the WRR, and if so, how'd it run?

Yes, you do need one nachtflug.

I put mine on this evening. Perfect fit. Check it out.

1) Stock ... 2 white plastic pieces and nothing else.



2) New ThumperTalk skid plate



3 & 4) Skid plate installed.

Hummm... I think the ThumperTalk plate might be the Utah Sports Cycles Ricochet plate. I orderd one today from Utah Sports Cycles and the part number came up as 463. I believe that's the same number we are supposed to request from ThumberTalk. Fascinating.

i bought the yamaha factory skid plate. the aftermarket plates are so big they vibrate and amplfiy the sound of the engine. at least they did on my lc4 and my crf.

I noticed thatg last evening when I went out to the Richoet website. From the pictures, they certainly do look one in the same.

I haven't had that problem (vibration and noise) on this bike or in the past. I wanted full coverage ... I have had a few arguments with rather large rocks in the past ... for me, more coverage and protection is what I need.

Norshor ... what is a ditch donkey?


In my experience with GPS and bike speedos the percentage the speedo is off is not constant. 80 mph on the speedo would be 8% optimistic over reality. I've found though that as you get closer to the top speed even the percentage of exageration is off. I found that on a KTM LC4, a smaller suzuki and a Honda V45 magna.

So ... Can anyone get a gps reading of what the bike is really doing when the speedo says 90 mph? Please don't endanger yourself!

Also check the Jap and Euro websites for manufacture posted hp..

If it's possible I'd love for someone with GPS to post how they got their top speed. IE To what velocity will it accelerate to strongly or how fast on gps after a quarter mile etc.

For instance on my LC4 400 it accelerated hard to about 65 mph, and then steadily to 73 mph. I had a large (56 Liter) givi box on the back that added lots of drag at those speeds. Those speeds are riding normal, no tucking, no tail wind etc. From 73 it took about 15 seconds of full throttle to hit 78 and then continuing to keep it pinned it would climb from 78-83 in another 45 seconds.

I was wondering on the WR250R if you were cruising on the freeway at a gps 75 mph (cuz the indicated would be much slower and cars are usually more accurate and would run you over if in your fantasy you thought you were really doing 75 - not bashing anything - just pointing out what I have found to be an important safety issue) if someone didn't see you and pulled into you from behind/the side, at that speed if you downshifted and pinned it, can it lurch forward, or is 75 at the end of the strong accelerating?
