In 1905, Continental Motors was born with the introduction of a four-cylinder, four stroke cycle L-head engine operated by a single camshaft.
The TT bike had a Unit construction powerplant, with a bevel-driven overhead camshaft.
Notable race modifications from the passenger car engine include a re-chipped ECU supplied by GM India, K&N Air filter and tuned Free flow Exhaust pipes while the Head, Block and Camshaft remained the same as in Stock.
The TN360 uses an air-cooled two-cylinder 354 cc engine with a single overhead camshaft,and was adapted from the Honda CB450 motorcycle.

Unveiled in 1966, it was one of the first production overhead camshaft designs to use a rubber toothed belt to drive the camshaft from the crankshaft (an honor shared with the 1966 Pontiac OHC Six, and also the Fiat DOHC engine of 1966), a method developed in 1956 by Bill Devin.
