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.
Constant competition led to quick improvements in the model line, leading to the MC21 generation that was unveiled in 1990. 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 welcomed the “SP” model, a bike differentiated by its dry clutch, adjustable suspension, and magnesium Magtek wheels. 1990 SPs had a Cabin Cigarettes livery; only 2,500 examples rolled off the assembly line that year.
This example is VIN: MC211014510. The seller purchased the bike 12 years ago from a private party in Northern California.
During his ownership, the seller has covered “a few thousand miles.” The odometer shows 39,257 kilometers (24,393 miles). He notes however, that “I honestly can’t confirm that. Those gauges are so easy to swap, but I can confirm everything on that bike is like new from Clutch to motor which has less than 500 miles on it since rebuild.”
Maintenance:
Per the seller: “The motor was fully rebuilt by Performance Engineering/GT Motorcycles in England in late 2015/early 2016. The motor has probably less than 500 miles since the rebuild. The cases are not stock, as the builder kept them.”
He adds “I have only ever run leaded C12 race gas in it.”
In preparation for the listing, he had us clean out the rear brake line and replace the brake fluid, the coolant, and the transmission oil. We also replaced the taillight bulbs, replaced the petcock o-ring, cleaned and synced the carbs, and serviced the chain.
