I'm getting ready to machin a 60T for my f4i and can't deside what size chain to run. The sprocket is gonna be made out of steel, then custom powder coated for a pimp look. What size chain are you guys runnin? I was thinkin 520, or 525, I don't care to much about rotating mass, cuz I'm not racing this bike, I just want cheap and long lasting, so break knowledge, lol.

 

I'd run a 525.

 

RK 520 has the same tensil strength as a 530 stockie..

 

rock a 525 dont go spend money on something youll never notice while stunting, plus if you get a 520 now and down the road find out you want a diferent size sprocket your going to have to special order a 520 no matter what size you want, i had a 520 while riding street for more power but as i went to larger sizes i had to special order evry one everytime , sucks !

 

one more vote for 525

 

All chains are strong we know this, but Sprocket wear is much faster on piece of shtt 520's. teeth wear/worp/break alot sooner then 525 n 530, if u want your sprocket to last go 525 or 530.

 

sounds like 525 is the winner for me, now I need to find a front sprocket and some chain to go with this big *** 60T I'm about to cut out on the cnc!

 

you should CNC some steal rear sets for all makes n models of bikes.

 

Actully, I'm making some street pegs and billet aluminum rearsets for my f4i also, they will be strong!

Like this one right here that I make for the derbi, but with a folding peg its 5/8 thick aluminum!

 

sick, if i had access to a CNC machine i'd make all kindas of shizzle.

 

I'm buildin 5 bikes right now, lol. Lots of billet!

 

well just let me know when u want me to come down to CA with my bike so u can hook it up.
