Best top and bottom end on the market!!

I've been ridding mx for years and have tried a few top and bottom end kit but the price and the quality of this kit is amazing. Plus the power of the bike from the stock it astounding, the bottom end power is through the roof. To anyone who is not sure weather or not to buy this, it's a must.

Q: Bearings?
Over 12 months ago
what bearings come with the kit? I see the 2 main bearings but it seems like there are 2 roller bearings and I believe my 2006 Honda crf 250r has a main ball bearing and a main roller bearing.

Q: Should I or no?
1 year 7 months ago
Should I get this for my 2012 crf 150r or no? It has 80+ hours of riding and about 50 of it is high rev riding on tracks and trails. It seems fine but I feel like I'm topping the motor out when I ride and I'd rather do this then let it burn out.
