Mapped on the PDQ Motorcycle Developments rolling road at 218bhp and 133 lbs/ft at the rear wheels (dyno sheet available).

Fully stripped and rebuilt by Mistral during winter 2022-2023 and not run since. Work undertaken included cutting and lapping of valve seats, replacement of piston rings, shims, gaskets, bearings, spark plugs and oil filter.

Included within the asking price are the throttle bodies and Pipercross air filter (if required).

Engine will be supplied with complete history file spanning the last 10 years, including details of all work undertaken by Mistral, invoices and correspondence. The engine will also be supplied with the Mistral engine build sheet and dyno sheet.

This is a very competitive engine and was a regular Midland Hill Climb Championship runoff qualifier in 2022 (with a best result of second) and a Gurston Down Top 10 Runoff Championship winner in the hands of its previous owner.

Excellent technical assistance and spares support available from Rob McDonnell of Mistral who built this engine and has refreshed it several times over recent years.

Previous best times when fitted to my Force SF included:

·         Loton 47.90

·         Prescott 39.38

·         Shelsley 27.32

·         Gurston 28.75 (in the hands of its previous owner) 

Priced at the fraction of the cost of commissioning a new similar specification Hayabusa engine at £10,950 ono.

Only for sale as I have acquired another similar specification Mistral Hayabusa engine and can’t justify keeping this as a spare.

Located in Cardiff CF5.
