dragster/runner wheels

[dragsterjohnny]

i have a runner 125 engine in my dragster. old "fx" i think, has a bigger disc than front. the std dragster wheel are ugly and was wondering if the new runner wheel would fit on the rear. i found out the "nrg" wheels don't fit because the caliper catches on the inside. also my scooter shop try'd a wheel that looks like an Aerox but with 5 holes but the valve was on the other side. then i thought what about the new runner wheel!...... can anyone shed any light on this?

If your engine is a gilera runner and a rear drum brake it is a fx if a 125 or fxr if a 180 an there are many different wheels which fit it all depends on the outside diameter of your brake pads as there are two different sizes .. and if it's a disc brake on rear it's a sp engine where 125 or 180 ...the only difference between sp engines are the nut on the outside of side case (later) or in side (early) at rear where clutch is ..if that makes sense ...so which do you have as you say you have a fx/r engine but u have a caliper which to me means disc ? an if it's disc only the drag or sp runner wheels will fit
