TESTIMONIALS
“ WOW. What an improvement. It is like a different bike. Much smoother and the power is everywhere. It does not matter if you are at 2000RPM or 4000RPM - it pulls like a freight train. ”
2002 XL883R with 1200 Torkster Kit

“ WOW! Let me make that perfectly clear, WOW! Totally different machine, I wasn't very satisfied with the Limited before the change, non-responsive, hard time riding under 2000RPM. Now - totally responsive at any RPM! ”
2014 Limited with Zip Kit
