The Honda CB750F is a special vintage Japanese motorcycle. It is responsible for bringing the inline four cylinder engine configuration to the commercial market, a layout which went on to become the most popular for sports bike engines for years to come. 

It’s influence on subsequent engine designs meant this Honda Bike became the inaugural ‘superbike’, a title that has since been sought after by many production bike manufacturers. The motorbike’s popularity encouraged Honda to re-issue various models of the iconic CB750F from 1969-2003.

These motorcycles have straight-four engines and are meant to be ridden fast. With our replacement Honda pistons, you’ll be able to get the speed out of your CB750 that it was designed for, whether it’s 20, 30, 40 or even 50 years old.

Our Honda piston kits give your Honda bike the upgrade it deserves. We believe the quality of new replacement parts should match the quality of the motorcycle it’s being fitted to and we go the extra mile to ensure our products are first-class.

We have been motorcycle piston manufacturers since 1989 and design our Honda pistons to work exactly like the original parts. Our products are shipped worldwide from our base in Cheshire and we have specialist stockists based in the UK, Canada and the USA. Let us restore your engine to the speed machine it was meant to be.

This conforms to the required percentages of specialist metals, the most important of which is silicon. Silicon has been proved conclusively over a prolonged period, to give the best ring groove wear rates coupled with a low coefficient of low expansion rates. Strength has been achieved using a modern construction technique which has allowed the weight to be reduced in the piston. The weight of the piston is the most important factor in engine design, since the effect of reciprocating weight is transferred directly in terms bearing loads, engine balance and maximum permissible speed. The lighter the pistons are, then the lower are the loads on the crankshaft main bearings.  

IMD have achieved piston weights comparable with the original parts, and will in the future improve upon this through innovative design.

This reduction of weight is now common place in automotive piston manufacturing worldwide, our pistons conform to this industry practice without any compromise, and are kept to the lowest level concomitant with adequate strength. 

Please note: All motorcycle & automotive components supplied from this site/listing must be fitted by a qualified Engineer using the correct appropriate equipment and using the necessary technical information. No liability can be accepted for components incorrectly fitted, and any such failure after installation.
