Bikes are only as dangerous as the people riding them really. Every sunday all the bikers are flying past my house (a 30 mph road) & flying down the country roads, overtaking us at blind bends etc, its no wonder they crash.

Ive only got a 50cc, but I dont really see why I'd need anything bigger atm. It gets me around & does 50mph which is enough for where I go, which is mainly in 30 & 40 limits anyway. I dont see the point in 1200cc bikes, when are you going to need that power? Will a 600 not take u over 100mph?
