The Ex-Denis Jenkisnon (‘Jenks’)
c.1975/76 TriBSA 650cc Hillclimb Special
Engine no. 6T 02806
This machine was built by ‘Jenks’ – renowned as Continental Correspondent of ‘Motor Sport’ magazine, contributor to many motorcycle magazines and 1949 World Champion Sidecar Passenger with rider Eric Oliver - circa 1975/76 using the original Triumph engine and Norton transmission from his sprinter ‘Greenie’- as offered in Lot XXX.

The frame is BSA A7/A10, its rear end modified to accommodate inclined shock absorbers, the wheels and rear brake are BSA, the front brake is a Triumph twin-leading-shoe unit and the fuel tank is from a Yamaha FS1E.

Jenks’s first event with his new creation was at Loton Park on 22nd August 1976 and the duo subsequently competed at Wiscombe Park, Hartland Quay, Gurston Down, Prescott and Shelsley Walsh. The bike’s hand-written notebook is included in the sale, “happiness is 7,500rpm in third!!!” (dated 4th September 1983) being one of one of Jenks’s more memorable observations therein!

The little bearded giant rode the TriBSA at Goodwood’s inaugural Festival of Speed in 1993 (page 40 of the Festival of Speed book) and it can be seen in the promotional photograph taken in front of the house. Indeed, when the first Festival was being planned, Jenks test-rode the hill on the TriBSA, which has the honour of being the first competitor’s motorcycle to sample the now famous Sussex course.

Informed that Jenks’s friends and executors wished to raise some money to secure his welfare after a devastating stroke, the present owner purchased the machine in September 1996, shortly before Jenks’s death. It has been kept in original condition throughout its present ownership, seeing competitive action at Brighton Speed Trials, Loton Park, Hartland, Gurston, Prescott, Shelsley and the Benjafield ‘twisty sprint’ at Cornbury Park. It was also displayed in the Jenks memorial marquee at the Goodwood Festival of Speed in 1997 and on a number of occasions at the BEN Lynwood centre in Sunningdale where Jenks spent his final days. Described by the private vendor as being in generally good condition, this machine represents an opportunity to own a unique piece of absolutely genuine Jenks memorabilia which also possesses a unique historic connection with the Festival of Speed.
