Got the xr250's top speed today

Recommended Posts

I used my friends handheld GPS and it records your top speed. Well my bike has the godrons mods, the baffle out, snorkle out, and rejetted. It topped out at 66.1mph, 1.1mph higher than i had thought it went. so im happy :cry:

Work on it some more. It should be more like 75mph. I have had mine up to 78 to 82 mph.

Depending on mods,

Dwight

Sorry, how is the question directed to? Me or Dwight? Probly Dwight, cause thats what u said at the start?

Yea we are talking about the 250, it did take a while to get up to 85mph, absolutly reving its guts out! going down a hill with a tail wind! That 6th gear helps alot!

I had my 1990 XR250 up to 140 km/h which is about 85 mph. All you need is the right gearing, plenty of revs and a looong staight!! :cry:

I'm with Dwight, I've had a stock geared XR250 up to 75. 65 seems pretty low.

My rev monster of an XR will do a bit over 80. :cry:

Whats an XR426 with 15/48 gearing going to do? Just curious, as I've had it going pretty good in 5th before, and was wondering my approxmiate speed.

On the XR650R group on Yahoo a member made a speed vs gearing Excel spreadsheet. It came with numbers for an XR650R, but with the gear ratios it can easily be changed for any other bike. The owners manual used to have the transmission ratios in it (mine does); cant say about the new ones though.

When my 2002 xr250 was bone stock (and still corked) i had a friend pace me in my truck. I got up to 68 on a flat road and still had revs to spare. I wanted to peg it, but I chickened out - I ran out of road.

Gearing matters a lot in determining top speed. My KTM with 13/52 gearing tops out at "only" 80. My xr250 at about 65-70. Not sure why this matters since 90% of my riding is below 40mph anyways.

This morning I got my stock-geared,Gordon-mod'd 250 up to 72 or so, mighta gone a little faster but I lost interest (READ: got skeered) at that point!

This was using the new ATK speedo that it seems we all jumped on.

Stock gearing, Slightly larger carb, big bore kit. I have had my 270 up to 78mph, I had a 285 up to 82. My 300+s would do about 78mph.

UNI FILTER, REJET, Modified snorkle not removed, NO BACKFIRE SCREEN. 1983 ATC250 exhaust diffuser.

Cher'o,

Dwight
