These cams are the best we have found for different riding styles. We tested over 15 different cam profiles for the TRX700XX before we were happy with the results. We use these in our race bikes with great results. Don't settle for a cam that might make you go faster get one that is proven to make you go faster.
*Stage 2 cam is for a mildly tuned engine that is made for endurance racing we use this exact cam in wayne matlocks engine. It makes good all around power with no bottom end loss and good mid range gains. Core charge applies.
*Stage 3 cam is for someone looking for more top end power. This cam makes solid hp and works great with more mods like porting. This cam has a very agressive ramp angle which requires the use of modified rocker arms. The rocker arms are by web cams and like the cam there is a core charge. These rocker arms are clearanced for the large cam and the face is hard welded to put up with steep ramp angle. Also you will need a valve spring kit to support the extra lift. Don't let the complexity turn you off, this cam is proven reliable and very powerfull.
