Engine Details

A very British motorbike

Thanks to Triumph Motorcycles Ltd for sending us the CAD drawings shown on this page.

Enigma 1050 triple engine CADdrawingAs we have remarked elsewhere, the 1050 Speed Triple engine that we will be using in Enigma 1050 was laid down before the arrival of stacked gearboxes. It’s a bit long, therefore, and it is also quite heavy, but the power characteristics are superb.
CAD drawing of Triumph Speed Triple 1050 engineThe drawing above shows the standard twin silencers. We will be using a single made to order item from Austin Racing in carbon fibre mated to the original headers.
Enigma 1050 crankshaftThe 1050 crankshaft is phased at 120 degrees. Pistons operate under a compression ratio of 12:1. Primary drive is by gear.

enigma 1050 camshaftsCamshafts operate four valves per cylinder. Drive is by conventional chain from the lefthand side of the crank.
Enigma 1050 speed triple crankcaseThe housings for the cylinder liners are incorporated into the upper crankcase half.
Enigma 1050 speed triple cylinder headLike the rest of the engine, the cylinder head is of a robust, conventional design.
Enigma 1050 speed triple gear clusterNo surprises in the gearbox either – a conventional design well executed.
