does it make a diffrence if i keep the 525 chain and upgrade the front and rear sprockets? i got a -1 525 front sprocket.. next ima do the rear which will be +1 525 sprocket.. which still lets me keep the 525 chain..

or should i just convert the who thing to 520? money isn't the issue the performance is.. been saving up some cash lol..[/align]

 

if money isnt the issue and you plan on taking the bike to the track do the 520 thing
but get hardened AL sprockets to maximize weight loss.

the best weight you can take off a bike is rotating mass because the centrifigual force of everything rotating makes the bike behave like it is heavier. the more you take off the more repsonsive in handling. its that whole objects in motion principle.

 

520 kits are cheaper than the 525.....

If anyone from here would ever get back to me on being able to advertise I would offer up some good deals on these.
