Chain and sprocket combo

the combos are the way to go, sorta wish I would've gotten the gold chain for looks but nobody sees that after the gate drops. I've only put 4 motos on the kit and everything still looks good.

Good sprockets

The sprockets are light and haven't cupped significantly after several rides. They installed easily on my yz125.

I bought this for my son's KTM 65. It fit perfectly and streched the power band out just as expected.

Choose wisely!

Combo is great, but be aware of the length of chain you need! several of the chain options are different lengths and they don't all work all the time. Ordered 120 link chain for a KTM 85xc and needed the 130 renthal chain... Should have checked, but assumed all listed would work and had to return, etc. Just added some time, but Motosport was great on the return.
