I recently raced my first harescramble and motor wise i think im fine, the problem i had is my 400 beat the crap out of me so i want to do some things, first off my left wrist was killing me from squeezing the clutch lever next was my arms was so fatigued i could hardly even finish. I know diet and excersise will help but what are some other things i could do to bike on $800 Dollar budget. Please let me know brands and where i can purchase whatever items you suggest and maybe even prices if you know them.
