Enfield 612 GTC Prova

Enfield 612 GTC Prova

New Enfield GTC 'Prova' motor
stroked to 612cc


Enfield collection

There's always a “back story” behind every bike we build and this one's no exception…

The Enfield factory in… India, mesmerised by our raucous styling expertise (!...) asked us to design and build a prototype that would give their iconic single cylinder bikes a new lease of life.

And there we have it; with me smiling whilst typing these notes…

Enfield Rear

Based on a brand new iconic Continental 535 GT EFI Enfield but transformed into a SoCal Desert Sled on 2 x 19” wheels, 612cc carbureted and stroked motor, peanut tank, Beringer racing calipers, discs and hand controls  together with many more custom applications as listed in this specsheet.

Enfield Front

Specced up by JETS’ Jeff Duval and rebuilt from scratch by Moore Speed Racing based in Poole in Southern England, it has now come back from Best in Class motorcycle paint shop artists Image Custom Design of Camberley near London.
And… No!... It wozn’t thankfully ever be painted black for sure!...
