This engine and the Velocette 500cc engine are likely the coolest looking Brit singles ever made.
They make a beautiful KIT to convert it into a vintage TRIALS bike.
I love the looks of the old Enfield or Ariel trials bikes at vintage events.
Here's a nice looking one I saw on ADVRider, I'm thinking about picking up one of these locally that someone put up for sale to tinker on.
Looks like a real motorcycle
I love Thumpers!
