112 momentarilly on GPS on course chipped tight packed dirt road in OZ,get of the packed in stuff and it spins up and slows down.Anywhere else all i can get is 108.
It's all scary shit though.
Slightly modified,15/45 new Michelin AC10 rear.

If your not @ top rpm it's the winds fault your Hp can not over power the drag.
In my earlyer post I mention not getting to the top into the wind ,I also reach top speed in 4th into the wind .
50 hp is only going so fast because of the wind drag no matter what gear ratio.

I could only get 96 mph this weekend on a gravel road. Had a high cross wind and tire was spinning.

we were talking about the garmin top speed anomiles (sp) this weekend. my old street pilot III has never given a strange reading.. though my buddies showed his top speed at 230 mph this weekend.. :applause:

My trail tech computer has read 95-98 freshly calibrated. 5400ft, uncorked.

my 85 XR600 would do about 93 or so. stock gearing, opened up air box, very leaky supertrapp.

i gotta think a 650R oughta do better than that.


my 86 600r does a good 90+ and still pulling....
mind you iam at sea level..when i say sea level ...its just over there..
cold too..think it all helps.
