In the mid-to-late 1980s, the small-displacement race replica market in Japan was booming. Legions of bright-eyed young riders were lining up to fork over their hard-earned yen for competition-derived road-legal runners like Yamaha’s TZR250, Kawasaki’s KR-1, and Suzuki’s RGV250. Manufacturers on the island were battling it out on the race track and in showrooms in an ongoing arms race to produce the most trick race bike for the streets. In 1985, Honda launched the NS250R MC11, laying the foundation for its line of quarter-liter oil-burners that followed. The NS featured a box-section aluminum frame and swingarm, disc brakes, full GP-style bodywork inspired by Honda’s RS250R factory race bike, Honda’s Astralight rims, and a liquid-cooled, 249cc, 90-degree V-Twin engine, two-stroke engine that made 45 hp (at 9,500rpm) and utilized the ATAC (automatically-controlled torque amplification chamber) power-valve system.
Timing of the RC valves were now controlled by a PGM-III ECU, it featured the iconic Gull-Arm swingarm, close-ratio gearbox, and smaller wheel diameters, which dropped from 18″ to 17″. Performance enthusiasts were glad to hear that the “SP” model made a return, differentiated by the dry clutch, adjustable suspension, and gold Magtek wheels. 1990 SP’s had a Cabin Cigarettes livery, 1991s were adorned with a Pentax paint job, 1992 brought back the legendary Rothmans scheme and in 1993, Honda made 900 of the SP’s in the HRC flash colors as a “Winner’s One” edition.
Many of these bikes saw the track and few survive today. Per the seller, this example (VIN: JH2PC2504NM101821) “has been in the US for many years and was originally assigned a 17 digit VIN, it is titled as a 1992 Honda CBR600.”
It was completely disassembled in 2019 and rebuilt with many new modifications and parts. “All the following parts and work has less than 100 miles on it:”
New Tyga bodywork: upper cowl, lower cowl, and front fender. It also got a new OEM tank and tail cowl, and everything was repainted in factory 1993 SP colors.
Engine completely rebuilt by Tyga Performance, cases vapor blasted, rebuilt crank with new Koyo bearings, complete OEM Honda top end, new reeds, clutch, seals, plugs, exhaust gaskets. All engine hardware re-zinced. New synthetic Motul 710 injection oil and 10w40 synthetic trans oil, fresh coolant and synthetic DOT4 brake fluid front and rear. M-Max derestriction box for PGM.
Per the seller, the bike is “nearly flawless cosmetically” as it “was completely disassembled and every part cleaned, inspected and lubed before reassembly. You could eat off the engine. Paint work is all new, wheels just powdercoated, very little corrosion or wear on chassis.” Mechanically, the seller says that there are no issues and that it is “like a new bike!”
