\"Sunbeam<\/a><\/p>\n

Following on from the successful production of pistons for OHV 500cc Sunbeam models Chris Odling and I thought it would be useful to produce some high-quality forged pistons suitable for the Model 6\u00a0side valve long-stroke. The Model 6\u00a0was produced from 1922 until 1939 becoming known as the Lion after takeover by ICI. With its 77mm x 105.5mm bore and stroke this was the last side valve powered motorcycle to win a Senior TT.<\/p>\n

There were of course changes along the way and the piston produced is nominally compatible\u00a0with models produced from 1925 until 1929. Before\u00a01925 a 5\/8″ gudgeon pin was used rather than the later 7\/8″ type and the change to a scavenge pump from total loss oiling in\u00a01930 means a different piston ring configuration is required. It is possible that these pistons could be adapted to suit.<\/p>\n

I have limited availability of pistons in 77.0mm +0.000″ and +0.040″ sizes. An all-up\u00a0 weight of 434g has been achieved for the 77.0mm which is within 2g of the target weight that we set out to achieve.<\/p>\n

Once we have given the new items a good look-over I’ll be contacting those who have reserved pistons already and adding them to the Sunbeamland shop<\/a>.<\/p>\n
