bgm50cc alloy cylinder kit, including cylinder head.
High quality casted alloy cylinder kit with an ultra hard wearing Nicasil plating. In terms of the thermal coefficient alloy is far superior to cast iron. This makes the kits running cooler and hence they can be setup leaner and/or with more advanced ignitions, so they even able to produce more power. Not without cause all the High End racing cylinders are made out of alloy.
Except for the material used with these kits the alloy kits are manufactured to the same specifications as the standard items. The combination of fairly conservative port timings with the fine alloy composite gives an ultra reliable and long lasting cylinder kit. As well a good choice if you have to convert back to 50cc unreckoned.
Last but not least is the amazing price of the kit. A real bargain! So you don't have to think twice if you take cast or the superior alloy.
Conclusion: If 50cc than at least alloy!
