This Harris Suzuki was one of the first produced by CR&S, with machine preparation by Domenico Pettinari. (Pettinari’s CV includes heading up the well-funded Bepi Koeliker Triumph racing department in the late ‘60s and he’s worked at World Championship level with star riders Gianfranco Bonera (Yamaha) and Gaston Rahier (Gilera) to name but two.)
By way of a Yoshimura kit, the standard 1,074cc Suzuki engine (no. V715-100677) has been enlarged to 1,340cc, and with four 41mm Keihin flat-side carbs it’s claimed to produce 170hp at 14,000rpm. The Yoshimura parts include cams, timing gears, valve springs, engine covers and 4-into-1 race exhaust, and these are complimented by 80mm Cosworth pistons, Carillo rods, an RK timing chain and more. A 22-litre alloy fuel tank sits atop a Reynolds-tube Harris frame with a braced aluminium swing arm and Harris rearset assemblies. The front forks are 42mm upside-down units, adjustable for compression and rebound damping, while at the rear there’s a multi-adjustable Ohlins monoshock attached to a rose-jointed rising-rate linkage. The 17-inch wheels are of 6-spoke pressed aluminium design and braking is provided by twin 330mm floating discs with 6-piston Performance Machine calipers, with a single 220mm disc and 4-piston PM caliper at the rear.
As one of only five Harris/Suzuki/CR&S machines built, the bike was purchased new from Roberto Crepaldi in 1995, and it has remained in the same ownership since then. It was also the subject of a substantial feature in the April 1995 issue of Motociclismo magazine, Italy’s leading motorcycle monthly. With an astonishing power to weight ratio of 966bhp per tonne, and the very best chassis and ancillary parts, this high-spec bespoke motorcycle would, in the right hands, be a very quick track-day weapon and/or a highly competitive steed for post-classic racing and parades.
