no problem. i have two kids and would like to come home to them every day thats my deterant. i also work for a living and cant afford to wipeout my daily driver. ya i know the katana isn't the ideal bike it was just a thought. a twin would be the best for torque. i like hawks a buddy has one but wants to much for it and would probably cry when i drop it. i'll look into a sv650. its a bit longer than a cbr or gsxr isnt it. do you guys know if you change both sprockets or just the back and how many tooth more i should go. unless there are sprockets specifically for this purpose. a cbr 600 or gsxr 750 would be alright to but people want to much for them. unless i can find one thats already in bad shape or was written off.
