The problem is the Chinese have not been able to create a high compression 4 cylinder engine yet, who ever heard of a 650CC motorcycle having such poor performance. I had a 350cc Regal Raptor Daytona, it was a pile of rubbish, scrapped it with only 8500KM on the clock, forever going wrong, ICU unit replaced after 4000KM new chain, to many things to mention, but the main thing that used to upset me was other Chinese Motorcycles such as Dayon, just fly past me and I have no response, they are 125CC. I think the Chinese have got the looks right but they really need Japanese technology for their engines.
