To simplify your options, we have categorised our performance items into a series of kits – with an indication of the percentage performance increases you can expect from an engine in a good state of tune and correctly timed. However, for more information please call and discuss your particular requirements: the power you need – and where you want it.

Please note that the kits do NOT include gaskets and other related items required to fit them – please source from your usual BMW supplier. For further information see the individual components under the ‘Engine’ section, and see the power curves under ‘Technical’.

While the R: Plus 18% tuning kit is easy to fit for anyone competent in motorcycle maintenance and with a suitable torque wrench, the others all need professional expertise – and to assess whether new seats and/or guides etc. are required. This is also the ideal opportunity to gas-flow the cylinder heads and liberate the full potential of your engine.

We would be pleased to quote you for fitting these kits and any other tuning work required. Please call for details. There are only two other concerns who we would recommend to fit these items/modify your engines...

Applicable engines are all R100 models built since 1985.
