Perfect for its price. I made it 53 with stock crankshaft, 24 carburetor, 24 apido exhaust and wild aasa camshaft, on a round-headlight model. The bike was beating Crypton X, that's all I have to say, get it 1000% but don't modify it, its gearbox can't handle much torque and as a result, it stripped 3rd gear after a lot of strain and hard riding. If you modify it, use Astrea gearbox and you're safe. I replaced it with the 150 from Lifan and I regret it, the bike goes only slightly better (10-15km/h top speed) and it's been nothing but trouble. The 110 is immortal, it just needs care.
