Zip R3i Tuned Here is a little short vid of my tuned scooter. It was a 50cc but I bumped the jug to a 70cc with a few mods, I need a better cylinder though. Like a Malossi 70cc single ring Aluminum with a max rev of 12k. Currently I can top out at over 60MPH (Spedo goes to 55MPH, I bury the thing if I tuck). I was flying past a bunch of local Vespa riders and their 100+cc manual rides when I blew my final drive due to an undersized belt (like a couple mm too small) that caused too much tension on the pully and chewed up the case till the bearings disintigrated. And dont think that something this small cant get a guy like me in trouble. I have laid it down once on accident the other time I was being a jack ass doing a wheelie by my old shop (days after I got it). I also have been pulled over for spinning the rear tire at a red light.
