if you wanna see some insane on-board video footage from a turbo R1 check out FuelMedia go to the 'movies' pages and scroll down. All the vids there are well worth downloading. These dudes are just plain mad :)

All new Motorcycles from Japan are limited to 186MPH/ 300 KMH. Speedo error is good for about 11%. Even though peeps are seeing 330 plus KMH on their speedo, they are not going that fast.


Since when are they limited to 186MPH? :) My buddies stock Hayabusa was clocked at 197MPH!

The speedo on my 600 was reading 154 when I was clocked at 146, so I agree there is error on most speedo's, but it varies bike to bike.



Trust me, they are limited to 300 KMH; 186 MPH. As of 2000 I believe.

Please do a search on the internet as I'm too tired to find it right now.

And once again, speedo error is about 10-11%. Even worse on the older cable/speedo motorcycles.

186mph is the limit from the factory, but doesn't mean you can't change that with some effort.

Any tips to get rid of the head shake at high speed. I'm probably doing about 70-80mph when she starts snaking and gets worse from there. I've heard about raising the forks in the trees helps. Has anyone done this and how much? I will probably buy a steering dampner later this year, don't have the bucks to spend on it right now. Are there any other tricks and if you raised the forks in the trees what about the rear suspension. I'm 170lb's. :D

Actually you lower the forks to gain stability, but you loose quicker handling. So when you loosen your bolts on your triple clamps you push the top of the forks down.

Before doing that I would make sure your suspension is in good working order. Grease your linkages, make sure forks have proper oil. Then make sure you sag is set correctly. Then that your clickers are set to the correct settings. This will take care of most headshake issues. After that is when you want to try moving the forks in the clamps.

Raising the forks will make it WORSE :) than it is now. Lowering the forks gives you more stability (more like Harley geometry), raising the forks makes it turn quicker (more like an R1). Since I fitted my MT18 front I found I need to raise the forks to get it to turn in on hard surfaces.

I did not mention anything about that. Just the stock limitations.

Much of the high speed instability is most likely the result of unbalanced wheels, especially if one or both wheels have only a single rim lock. It is easy to balance the wheels within an ounce with the wheels off the bike using a pair of jackstands.

Done 167mph on my VFR750 in 99. Of course that was before a car pulled out in front of me doing 30mph and messed me up pretty good. Now I'm restricted (by the wife) to offroad were I managed 87mph on my 04 WR450 in the sand.

I pulled my GPS out of my backpack during a ride a week or so ago and was astonished to see it read 92.5 mph!! I did some speed runs once and barely pulled 80mph but my jetting was still not fully worked out then... my brother thinks my GPS freaked out and mis-reported the speed but I have used it for a long time and never have seen it do anything like that. What do you guys think? There were a couple roads that were very smooth and maybe a bit downhill....

I got the TRE mod for my bike which takes the 186MPH limit off and also the timing retard in 1st-3rd. Made the throttle a lot smoother through 1st-3rd. I had an '01 and '02 that both had the 186 limiter.

YamahaSteve that is really close to what I ran with my 2003. I got the 90.1 with my GPS. As far as the GPS doing something wierd, I have driven 1000's of miles with mine on the dash of my truck and never had it do anything wierd with speed that I saw.

Got 160km/h on speed trap over quarter mile. This was at an official street racing event held in my hometown. Traffic department of the municpality supplied and managed the speed trap. Acording to them the trap is perfectly calibrated and highly accurate. My time was clocked at 13.44 seconds over the 400m. Was also first in class, some of the other speeds recorded...
Banshee - 152km/h
Honda CRF450 - 138km/h
Banshee - 141km/h
WR450 - 148km/h
KTM 525 - 140km/h
Honda CR250 - 121km/h

etc...


Standard wr450 '03. + rider on steroids... :thumbsup:

With a 15 tooth counter and a PC T4, my 03 WR450 ran 103mph (Garmin 12) on a section of street outside of Belmont Nevada.
