Reminds me of Malcolm Uphill’s 100mph lap at the IOM in 1969 on a production Bonneville. Not bad for a pushrod twin with drum brakes.Things have improved over the last 57 years!

Well I could drone on about the TT this year, but instead I will leave you with this fact, and resultant thought.

A 650cc four stroke twin lapped at 124.5 mph. How is this even possible, as the young ones say. 124. Sheesh.

Well for a start it's a purpose built 8 valve engine and chassis.

Apparently he only just made it home, as when they stripped the engine after the race they found the pistons were cracked from the gudgeon pin bosses to the crowns !. He did win another race, the North West 200 in 1970 on a works Bonneville with a lap average of 106 mph, he had the choice of the Bonneville or the Trident and chose the former. Development had gone as far as Triumph were prepared to go with the Bonneville and from then all race development was with the 3 cyl. Trident.
