Yamaha TZ750 crankcases
Kelgrif Patterns have been involved in a partnership to reproduce the famous Yamaha TZ750 crankcases. These motorbikes dominated the racing scene from their introduction in 1974 until the 1980’s. A lot of these engines then found their way into sidecars and as a result of the constant thrashing, most crankcases were broken beyond repair.
In 2014 a partnership between Kelgrif Patterns, Mulholland Foundry, Milspec Manufacturing and Team Ditchburn Racing began work on making brand new crankcases.
Ted Gorski spent 650 painstaking hours making all new timber patterns and coreboxes using a combination of drawings and the existing castings.
For more information on the purchase of these crankcases, please contact Gary Kerr.
