i don't wanna diss you but correctly it should be (R+M)*C

Good to know that RD is part of the 2t Taliban!

Better get yourself an eye appointment. You're due for a new prescription.

Thanks guys. Was a good night! Won my heat, won my semi, but got passed about two turns from the white flag in the main. Just a bone head move on my part... I settled in when I was leading knowing I had to just beat Aranda for the king of Zuidbroek and I let maillard get too close and he acted on my mistake. All in all, great weekend and yes, Suzuki’s can win... maillard is on a Suzuki .

That can't possibly be correct. He's riding a Suzuki, and everyone on Vital knows it's impossible to win on one.

Wow, motocross sure has come a long way. Back when I was young, we had to built tracks in green, lush areas that had hills and grass and shade trees to rest under. Sounds horrible, I know, but it was all we had. Nowadays, you lucky guys get to ride on the moon!!! Wait - that is the moon, isn't it?

This just in... Some old dude won!

Shy of SX ridnig, I haven't seen OEM chains break So I run the a new bike ALL STOCK for the first chain and sprocket change need - for me on a 450 that's 15 hours max. And I don't know why people push these to huge hour intervals. A broken chain due to neglect is super dangerous. This 15 hours allows me to understand the bike - and appreciate all the testing work the OEMS did. I run std bar bend, etc etc etc. After 15 I make a punch list of things to address - often times I...

you'll go through several chains, even o-ring, before you wear out a steel dirt tricks old school steel was heavy, dirt tricks has theirs trimmed out enough to get weight differences much closer. and they look amazing in person, pics dont do the zirconium justice. there's also black if you dont like the heat treated awesomeness look... and they'll laser etch your name/# on it for free...

Chain and sprockets wear as a set. I can't imagine some of you guys are seriously wearing out an aluminum rear to the point where it's not safe to run before the chain is also toast, it seems like they both wear out at about the same time for me so I replace everything as a set. If you put a new chain on a worn sprocket or vice versa you're going to get premature wear no matter what you do.

In my experience sun star are the best wearing aluminum sprockets. They are my go to replacement. The typical rental aluminum rear has got to be one of the worst.

Renthal (aluminum) sprockets are one of the for worst longevity. I swear they are made out of pasta....and they are expensive.
