Yamaha RD350LC Parts

Development of Yamaha RD350LC

The 1970s were ending and though RD 350 was still a very popular bike, times were changing. Riders demanded higher performance sports looking bikes, while governments all round the world were tightening their regulations on emissions. As such, Japanese motorcycle manufacturers had to come up with new solutions for the race-developed two-stroke motorcycles, and Yamaha RD LC Series was born.

Promising start for liquid cooled RD 

The “Two Wheeled Rocketship” as one of the early magazine review writers called it, was first introduced at the Paris bike show in 1979. This was a race bike people were waiting for!

The two-stroke twin cylinder old RD was redesigned by a multinational team including Brit Paul Butler, who was a team manager for the Marlboro Yamaha GP Team and later product planning manager for Yamaha Europe.  

Amongst the new features, the old-fashioned air cooling system was replaced with liquid cooling (thus LC model), new carbs were fitted, new separate cylinder barrels, new exhaust tuning, new LC engine steady bars and new reed valve all meant that the new Yamaha 350LC was meeting both the customer desire for a race bike and government regulations.

To finish the liquid cooled two-stroke off, Yamaha added other tried and tested features like electronic ignition, mono-cross suspension and disc brakes on the front wheel. The optional fairings were just a cherry on the cake. It was an ideal cross between the old Yamaha RD series and the TZ racers.

Rocky riding experience

The first production units of Yamaha RD350LC bikes had endless problems with leaking exhaust pipes and poor intake caused by the poorly rubber mounted liquid cooled engine. Both have been resolved in the later 1982 model, with new engine mounts introduced and improved exhaust system.

Compared to a modern bike, the original LC was said to be a bit wobbly and skittish, but back in them days, little handling issues were all part of the fun! Little design flaws had to be overcome if a rider wanted to race the RDLC two strokes back in the days. The most common modifications were removing the rear mudguards and indicator stems, so they might be the restoration nightmare to replace.

Power valve introduced

The life of two-stroke water cooled LC350 Yamaha was short-lived though, innovations to cooling and exhaust system were just one step forward for Yamaha, a whole new system was in making and in 1983 the Yamaha Power Valve System opened a brand-new chapter.
