My first motorcycle was a round tank RD200 like this in metalic orange, complete with ace bars and a handlebar fairing. Despite lots of fettling and chamfering of the brake shoes, the front TLS brake was largely an on/off device. It was surprisingly powerful for the size of the bike, but very 'grabby'.
On my driving test, the tester told me he would simulate a real life situation where I would have to do an emergency stop. As I rode down the road expecting him to leap out or something, in my mirror a car distracted me by flashing his lights. When I looked forward again, the tester was in the middle of the road right in front of me with his arms open. As I was caught by surprise in panic I grabbed the brake and did a stoppie that Toprak would have been proud of!
Amazingly, he passed me and even congratulated me on my brake control.
I kept the bike for a year and was planning to get a RD400. My dad said, he would loan me the money if I bought a Honda 400/4, as he liked them. I wasn't really interested, but I was desperate to get a bigger bike, so I accepted the loan. One ride on my first Honda 400/4 and I was smitten and any thoughts of another Yamaha quickly evaporated.
Hope you have as much fun with your Yamaha as I did with mine.

It's the one just before the RD,

No reeds,

I have a DTI,

The mileage is 480

Seems from the condition to be true,

Clean oil in the gearbox, plenty of compression


I shall just tidy it up, polish the scratches etc

Keep it with its patina

Ring a ding ding.

Nice one John.
One day I'll have the time to restore it, not just talk and dream....

Only spent a couple of hours looking around,

I connected a battery, the electric seem to work,

Does need various replacements

A few essentials, others cosmetic

Very nice John.

The Yamaha two strokes of that era always have a good intake acoustic, that induction roar as they come on power, quite distinct and charismatic.

A good bike for blatting around on this summer  :)

I used to have a CS3, slightly older version of essentially the same bike.  For a small bike it was surprisingly fast.  Sadly, being very young and a bit too keen on thrashing it, the crank failed, some of it seemingly blasting out through the exhaust pipes ;D

I'd love a good 2-stroke resto project...... very difficult to find one here anymore, and restored ones are worth mega dollars....  saw an ad yesterday, gent has 3 RD350's, one runner, one needs pistons, one needs a lot of stuff..... for the lot he's asking C$20,000.  The RD's are very desirable, but not that desirable, lol!!
