with all my aftermarket parts what would you expect my 250r to run top speed wise

 

it depends on ur gearing and tire size, but i would say no lower than 68

 

stock gearing and 18 inch tires

 

it should be around 65-70 on a nice day

 

I have some of your same mods, 38 airstryker, K&N, bored .40 over, esr trx6 (low-mid range) pipe and a 15 tooth front sprocket with 18s. According to a gps I can get 72-74 mph on pavement

 

Mine has fmf pipes, milled head, v force reeds and spacer, 275 ported for top end, k&n, 13/38, 18" tires and it does over 70 cause i was passin cars from the freeway on the frontage road. Im gonna have to get some1 to go beside me on a car to get the exact top speed.

 

I think with that set-up you should be running into the low 80s if you went higher on your gearing.

 

well i took a ds on top end and from what ive heard theyre supposed to do around 76-78 or something??? (just didnt wanna sound cocky and say that it did over 75) but im thinking of gearing lower for more bottom end cause top speed isnt really usefull to me...any suggestions?

 

Could see how you may want some low end power but a 13 tooth sprocket with 18" tires is really low, try a 14 front if you want a little more on top. The bottom end shouldn't suffer too much especially since you are a pretty light guy.

 

What if i put a 36 on the back? will this give me low or top?
