How fast is your bike?


Recommended Posts

85 mph at present gearing with dirt wheels (15/48 gearing)

95 mph (15/45 gearing on 17" wheels)

It would go a bit faster but it doesn't like it

Speed noted using a "calibrated" Trailtech endurance computer, standard speedos are way off, they can read 10 mph over.

All done on a private road of course.

This isn't scientific as I did not set out to do top speed runs, these are merely the top speeds I have seen.

Stock '95 XR600 14-45 gearing- 145 km/h or 90 mph apsolutely tapped out flat road

My stock XR650R 2001 14/41 gearing used to regularly pull 170 km/h or about 107-108 mph (thats silly speeds for a dirt bike!) tapped out on the same road!

Stock '2000 model XR400 that I had pulled 145 km/h or 90 mph flat out with 15/40 gearing and staintune aftermarket muffler.

2002 Xr650R-fully uncorked stock gearing. I got 103mph out of her. That was on an analog speedo, dirt road. It was nuts, haven't even touched 85 since. She stayed smooth though, thank god I didn't tap a rock.

You guys are recording some high top speeds. You must be having the valves bouncing and caning the nuts off the bike surely. If I rev it hard (with the valves bouncing) with 18" dirt wheels and 15/48 gearing I would be lucky to see 90mph. I could get 100mph on road wheels with 15/45 gearing but would be absolutely flat out.

Are you sure your speedo's are accurate? or maybe it's mine that is under reading!
