hi me and my friend are fighting about how fast the 250r stock goes. could somone just tell me how fast it goes stock

250 xplorer

scrambler 500

 

From 72-76mph I've heard.Tire pressure,air temperature,elevation and rider weight make up some of the reasons for discrepincies in speeds.

 

I concurr

 

i saw on a website 68,but couldnt it also depend on the year?to my knowledge 89 was the best or something(i basicly know nothing about 250rs)

 

this sound right. back in 1988 when the magazines could be trusted more and they gave topspeeds as part of the tests, they consistently got 72mph out of it. in june of 1988, 3&4wheel action (now 4wheel action) took all the bikes to a drag strip and they got 72mph out of it from what i recall.

 

I went on a website (can't remeber which one) last month that had a test of all of the 2 stokes from the 80's. The TRX250R hit 72mph. This is a little off topic but they said that the STOCK Quadzilla hit 81 mph........damn thats fast!

 

81 is haulin the freight. if the gears on the TRX are the same as the ATC, i disagree with all speeds posted to far.

 

The only changes they made threw the years where the swingarm, body looks, and lights on the 89's

"81 is haulin the freight. if the gears on the TRX are the same as the ATC, i disagree with all speeds posted to far. "

How much would it change with larger gears?

scranblertherest.. lets remember one thing.. it really doesent matter.. what uou should be worrying about is handling...

 

Were the transmissions the same from the liquid cooled ATC to TRX?

I think the TRX 86 stock gearing was 13/38 and the 87-89 were 13/39
When my R was stock with 13/38 gearing (but with 18" tires) I hit 70mph....I was racing our pet cheetah so I know that's accurate

lol

 

ok first the top speed is 70-72 depending on the year (this would be with original tires,gears, ect) The ATC's (85-86) and TRX's (86-87) all had 13/39 with 5th and 6th being a tad bit taller than 88-89 TRX's The 88-89 had 13/38 with a 200 RPM higher rev limiter. Also the 85-87 250Rs all had a slightly higher primary gear, therefor each years were very close to each other. LOL, now put a 15 tooth front sproket on the 250R and you will hit about 90.

By the way there was SO many little changes from 86/87-88/89 250R's its not even that funny....
