Very well made and cleverly designed cast iron cylinder kit made of a Minachrom-cast iron composit. The 70cc Version of the Trophy series is designed to give a high top speed with a considerable fast acceleration.
The 70cc Trophy could even be used with the standard components. The carb should be upjetted with a 5-15 larger main jet. For a decent, but very powerful setup a 17.5mm carb with an sport exhaust is recommended.
The porting layout is well suited for fast road touring and the nice transfer system gives a nice mid range power spread.
When it comes to reliability the 70cc Trophy is as long lasting as the bog standard cylinder.
