Seems like it is right (Checked both RaceTech & SonicSprings site) ... SonicSprings also lists 0.85mm for 220lb rider. You might as well talk to RaceTech and SonicSprings

Fyi - I am 172lb without gear and use 0.8kg/mm SonicSprings which is on the stiff side.

The bike is a little lighter than stock, snorkel delete and full carbon fiber Yoshi exhaust would be the only "significant" things though.

I weigh 215 and adding approximately 20 pounds of gear on that so we'll say 235-240 pounds for a zone. What would you estimate for:

A) a racing set?
B) a trackday/spirited riding set?
C) a commuter set?

I'll likely opt for option A or B, but I'm just curious. Judging by some of your guys' weights and riding styles is how I'm estimating I'm probably in the 1.0kg/mm range, I'm not a small dude lol.

Also, I'm installing the gold valve cartridge emulators with the yellow race springs so what fork oil weight and height would you suggest? I think someone previously suggested I should use 7wt or something super light like that.

Thanks!
