The Honda SL 350 was a Air cooled, 4-stroke, single cylinder SOHC Enduro motorcycle produced by Honda in 1969. Claimed horsepower was 32.99 HP (24.6 KW) @ 9500 RPM.

History

The motor was EXACTLY the same as the CB350 & CL350 models, same camshaft, same crankshaft, ignition, gearbox, etc. The only difference was the final drive gearing, and exhaust systems. The later SL’s had standard Kehin 24mm carbs that eliminated the aforementioned CV’s slide issues, and with a more restrictive exhaust system, brought the SL’s power down to 30 horsepower, from the CB’s 36 horsepower at 9000 rpm, and the CL’s 34 at 10,000 rpm.

And what a motor it was. The 350 Honda twin was anvil reliable, with over 300,000 copies being sold in the USA alone, it was one of the most popular motorcycles ever produced. When the SL350 got some knobbies strapped to it, and decent shocks bolted on the back, the bike became an unstoppable woods weapon, as nothing short of an atomic blast would cease the rear wheel from spinning. It was also, in my mind one of the best looking vertical twin cylinder motors ever produced, right up there with a Triumph or BSA in the looks department.

In 1974 the SL350 was replaced by the XL350, with the CB & CL being replaced by the 360 twin, a relative failure when compared to the 350. And you can still find a nice example of the 350 twin for cheap, since the 350 is still not recognized as a true “classic”.

Engine

A 63.5mm bore x 63.5mm stroke result in a displacement of just 326.0 cubic centimeters.

Chassis

It came with a 3.50-19 front tire and a 4.00-18 rear tire. Stopping was achieved via Drum in the front and a Drum in the rear.
