Hello. My name is Brad and new to these forums. I just put on my 15 tooth front sprocket and was wondering how far off my speedometer/odometer is now that I did this. Thinking about it, I would assume that it now reads a faster speed that what I am actually traveling, but my question is how much. Been searching around and haven't found anything.

 

it'll be off whatever it was before you made the change plus 1%

 

how do you like the new sprocket on there does it make a very noticable chance or not ive been thinking of doing it just trying to get some people opinions on this.

chace

 

the only to tell for sure is to either hit it with a radar or a dyno

 

What about a speedohealer? i've got a buddy who put a -1 +2 520 conversion on his 50th ann. R6 with a speedohealer and he doesnt seem to have any problems with his. i guess its even got a top speed recall on it.

 

50th ann. R6??? I'm reading this wrong, right? [&:]

 

Its definitely a noticeable difference and worth it for the price. I recommend it

 

I have a -1 on the front now, it's around 10.5% off.

 

So your saying that if the speedo is reading 55mph, really, I'm only traveling 49.225mph?
