i might be able to get a 05+ gsxr750 engine for really cheap 128hp at the wheel
how much better will a gsxr750 climb than a 500
both will be on pump gas (no nitromethane for me)

im hoping pstoffers will chime in here
I think more people would lean more towards the GSXR motor it makes more power and when your on the gas its going to handle decent, you will find alot more inline 4's on the pro circuit then a 500....NightBiker07 wrote:well, the weight difference would make the GSXR/MX bike harder to handle.
build a Liger 500 and dominate the competition :0
