I had a sucky Suzuki Condor III (it has 14 yrs right now) 49cc and i boosted it up to 80cc with a competition Exhaust by Yasuni and performed transmission, also I've a trial motorbike Merlin 370(old as hell too) that my aunt gave me and a 100% tweaked by me piaggio typhoon (evry piece changed to polini) but that was the one i used to move in city and i crashed with it, and i don't feel like repairing it...Anyways i'll stay away from motorbikes 4 a long long time (But i still dream on purchasing a SUZUKI GSX600R or a Honda CBR 600f or Yamaha YZF R6...Only time can tell...)
