Can anybody tell me the wheel bearing sizes for a 2011 beta evo please

Part number 6904 all evo front and rear available from your local bearing shop

Thanks for that kris

Neil, pop on ebay and buy stainless bearings instead of normal steel, another quick tip before you fit them pop the cover of with a stanley blade and fill the bearing with marine grease

The stainless bearing deal with the heat a lot better and last twice as long, filling them with proper grease stops and liquid corroding them.

I've been doing this for ages and bearing last me a long time, average cost is about £12 - £14 per wheel sometime i get them down to £10 per wheel
