It's Tha Heist, a 250cc US bobber kit from the Cleveland Cycle Werks which moves into the Kikker 5150 market in the UK

 For those of you at the BMF show this weekend, you will have seen the UK debut of the Cleveland Cycle Works bobber 'Tha Heist'.

It's a familiar format now, thanks to the pioneering work of the builders of the Hardknock Kikker 5150.

The latest little machine comes with a Chinese Lifan single cylinder motor, based on a Honda lump and built under licence then planted into an all US-built hardtail frame.
