1990 Yamaha XJ600

Chimera Motorcycles first build as featured in the Bike Shed London Show 2022.

in typical fashion when setting out on choosing our first build I wanted to use a base bike that hadn't really been used before which in turn means very little information available and even fewer available parts! 

I was looking through local market places and saw the regular Hondas and BMW's which all look fantastic when done and have incredible support online and with aftermarket parts but I wanted something not usually done before. I even have a 2018 Ducati Monster in the garage,

but i wanted something from the 80/90's ...

An ugly duckling....


And there she was a slightly dishevelled 1990 Yamaha XJ600, with horrible plastic fairings, clunky displays, proper 80's styling at its worst. 

Its claim to fame, the first inline 4 cylinder 600 that paved the way for many future Japanese superbikes
