This 1970 Honda SL350 Motosport was purchased in 2025 and subsequently refurbished with work that reportedly included over-boring and rebuilding the 326cc four-stroke parallel-twin, overhauling the carburetors, and refinishing the bodywork in Candy Sapphire Blue along with replacing the clutch, seat, wiring harness, ignition system, tires, cables, and more. The bike is equipped with a five-speed transmission, 19″ and 18″ wire-spoke wheels, preload-adjustable shocks, drum brakes, street lighting, an aftermarket exhaust system, and both electric and kick starters as well as a chrome cross-braced handlebar, a rear rack, and a side stand. This SL350 is offered at no reserve with a spare speedometer and a clean New Mexico title in the seller’s name.

The bodywork has been refinished in Candy Sapphire Blue with white graphics, and it is mounted over a silver-finished semi-double-cradle frame. The black vinyl-upholstered seat and the turn signals are noted as replacements, and other details include a 2.4-gallon fuel tank, high-mounted fenders, a horn, a side stand, and a rear rack modified to sit lower and carry the rear signals.

Wire-spoke wheels with chromed steel rims and drum-brake hubs measure 19″ up front and 18″ out back, and they were mounted with Shinko tires in 2026. A steering damper is in place, and suspension consists of a conventional telescopic fork along with a pair of chrome preload-adjustable shocks mounted to the swingarm.

The chrome cross-braced handlebar carries black rubber grips, dual replacement mirrors, and rubber-tipped alloy levers, which have been fitted with replacement cables. Nippon Seiki instrumentation ahead consists of a replacement 110-mph speedometer and a tachometer with a 10,500-rpm redline. The five-digit odometer shows 4,900 miles, approximately 10 of which have been ridden under current ownership. Total mileage is unknown, although the removed odometer showed 28k miles.

The 326cc SOHC parallel-twin is said to have been rebuilt under current ownership with a 1mm over-bore and replacement pistons and rings, along with a resultant displacement of 336cc. Additional reported work included machining the cylinder head, replacing the valves, and fitting a replacement ignition system and wiring harness as well as overhauling the Keihin carburetors, which have been fitted with cone-style air filters. The engine is also equipped with both electric and kick starters in addition to an aftermarket exhaust system fitted with factory heat shields.

Power is routed to the rear wheel through a five-speed transmission and a drive chain. A replacement clutch assembly and springs are said to have been installed in 2026.
