Greetings,
I really want to go to a 15 tooth front and 41 tooth rear sprocket for better wheelie ability and hill climbing torque, but I would like to preserve as much top end as possible. My riding partner has a Raptor and I can spank him pretty good at the moment, and I would prefer to keep it that way if at all possible? My DS is a stock '02 Baja, no "regulation" mods., but I have messed with the endcap a little! Any suggestions would be great!

 

Run a 21" or a 22" tire. That will give you more traction and still let you keep the top end speed.
