Used Buyer Review

The LEM LB50 R is a 50cc Italian-made mini motorcycle that sits in that awkward space between serious learner tool and glorified toy. For what it is, it's actually reasonably well built โ€” the Italian pedigree shows in the frame quality and switchgear, which feels a cut above Chinese equivalents. Used examples are typically found in various states of neglect, so inspect the carburettor carefully and check the variator rollers on the CVT, because owners rarely service these properly. Performance is exactly what you'd expect from a restricted 50cc โ€” adequate for urban commuting under 30mph but genuinely frustrating anywhere else. The front disc brake is a highlight, offering decent feel for the class. Suspension is softly sprung and wallows on broken tarmac, though it handles light road imperfections acceptably for short hops. Buy one as a first bike, a pit bike, or a cheap urban runaround. Don't expect longevity if the service history is sketchy โ€” these engines hate neglect. A well-maintained example at the right money makes sense. A mystery-history bike is a gamble.

Pros

+Solid Italian frame quality
+Decent front disc brake
+Easy urban maneuverability
+Reasonably simple mechanics
+Good parts availability

Cons

-CVT variator wears quickly
-Soft suspension disappoints
-Restricted performance frustrates fast
-Service history usually absent
