bought a sur Ron x black edition, I missed out on the ludicrous edition(only 100 made) , put it together last night and already want more power!! first off it's fun, it's a toy but it is fun, it does 42 mph and gets there pretty quickly. it will wheelie and it's super light, 110 lbs. having said that, I am 6'3 and 270 lbs, this thing is small, the suspension is probably good for a 150 lb person, the seat sucks, and the handlebars are low, however I can ride it on the canal path behind my house and it should be fun in the tight little woods across the street. I've ordered footpeg supports( I'm 270 lbs) , a 21 inch front wheel, 1.5 in bar risers that also move the bars forward and a 3 in. rise bar, 1.5 in. rear suspension lift, and a race tech seat that goes on over the existing seat/battery box which will raise it about 2in. more. I will probably be ordering a light speed 72v battery and charger and a bac 8000 controller which in combo should bring the little bike up over 20 hp, stock is around 8hp. these mods will double the price of the bike and bring the cost up into used Alta MXR range but I think I can get away with riding this on the road. does anyone have any experience with these bikes?
