The new 250 ninjas have 17" wheels

 

I've looked into this too. You could switch forks side to side to correct wheel direction so what if the caliper is mount at the front or rear. The down fall I found was rear sprocket choices larges I could find was a 45t. The work to jimmie rig woud be easier and cheaper in long run just to bite the bullet and buy a set rims and spokes to lace up. Rotor and sprocket alignment would be correct and stock replacements.

 

does ur bike go over 60 with a 53 tooth rear? I have a 14/47 and I feel like I need to put the 42 back on. lol

 

I drive mostly around 50 mph all the time. Can do highway speeds of 60 or 65 mph and doesn't rev out too high. It with still go faster but I don't rev it full out in top gear not sure of top speed yet. I drive through alot of hills and never have to drop a gear. I been thinking of trying a 54t. Its like driving without a six transmission if you do the math from stock. I never used sixth much as it was a dog. Now with some add on and the gear change it's a bear

 

wow with our flat land down here I think that I can go 60-65 with a 47 tooth without blowing the motor. Its really hard on it to run over 6000 RPM for too long.

 

ah oh, new toy.

 

ummmm... i dont know about you, but i run mine at around 7.5k rpms all the time. My engine has over 10,000 miles on it and its still running strong. I'm sure it could use a new top end pretty soon, but thats a given for something with that many miles on it.

do you have an after market pipe, or anything preformance wise installed yet? might help your bike out with the whole breathing restriction it comes with. good luck

 

Just shy of 8,000 miles and it spins a minimum of 6500rpm for most of them. Keep the valves checked/adjusted and it should be fine. Running that rpm is the same as driving my car at 60 mph roughly, both are 4000 rpm below redline. Keep on top of the maint. schedule and its pretty unlikely that you will hurt the motor in this thing, its not exactly fragile or high strung like a KX motor.

 

Guess U didnt read about my mods. I have a procircuit pipe. Airbox snorkle removed. Carb is jetted to 125 and 35 and air fuel screw out 2.5 or so. I am looking to get a little more but sadly I will have to get a 300 or a 331 kit to get what I really want.

 

i know how you feel brodie... just got off my buddies drz 400 yesterday... whoa! but i knew that was going to happen. i still love my green meanie. and i'll tell you this, its hella lighter then that drz is. i dont care if on paper it says like 30lbs diffrence or whatever, it feels like a ton of bricks in the woods. but thats just me and my opnion. (sorry for jackin the thread)

anyone have any luck with the ninja wheels?
