Classic Tales: 1986 Yezdi 350 Twin
Motorcycle owned by: Mukund Ayyangar
History: Ideal Jawa (India) Ltd was an Indian motorcycle company based in Mysore which sold licensed Jawa and ČZ motorcycles beginning in 1960 under the brand name Jawa and later Yezdi. The catchphrase for the bikes sold by the firm was “Forever bike forever value”
The Jawa 353/04 designated as ‘A’ Type, Yezdi 250 ‘B’ Type, Jawa 350 type 634 Twin and Yezdi 250 Monarch models are driven to this day in various parts of the country. Jawa and Yezdi bikes, especially the ones with fuel tank paddings and ignition systems on the fuel tank are now collectors items. The company stopped production in 1996.
There are still several bike enthusiasts in the country. There are several bike clubs across the country, some of them even organizing long distance rallies.
A Jawa 350 type 634 engine wedded to a Yezdi Monarch frame and only the second twin cylinder motorcycle ever to be launched in the country, failed to capture the imagination of the Indian two wheeler market.
Q) Mukund, tell us how and from where did you source this motorcycle?
A) I had gone for a trek to Karnataka, Kodachadri and Shimogga district. On the way back I stopped at friends place in Coorg, Virajpet. While staying at his coffee estate, I saw this twin engine being used to pump water from a well and it was doing such a superb job. When I stopped to find out what engine it is, I skipped a beat to see a Jawa 350 heart pumping all its power to pump out the water.
I asked the friend if the engine is available for me to take home. He didn’t even think for a second before saying ‘yes’.
The next moment the engine was with me in a bus back to Pune. Thus the story began where I spent 8 months just to collect all the necessary / stock material to put his bike all together.
- Engine – Coorg
- Frame / chassis – Pune
- Front brake hub – Mysore
- Fuel tank – Delhi
- Wiring harness – Banglore
- Instrument console – Banglore
- Other engine parts – Banglore / Mysore / Pune
The bike was all put together at Mane’s garage in Pune.
And videoed the first ride back home
Q) Is the motorcycle completely in a stock condition? Any tinkers done?
A) It is completely stock bike, the only modifications are the electrical for a better quality spark. I have increased the turns on the magneto coil therefore a better current.

Q) How does it feel riding?
A) It feels like a high revving raw two stroke power between your legs which knows only straight roads. I think the engineers didn’t foresee that there would be turns and bends on the roads in the near future. Because all this bike knows is to go straight. You can’t lean / or even try to bend the bike into corners.But it is a crazy bike with insane powers.
With dry kerb weight of 152 kg it was heavier than most of its peers in almost every category. The seating is comfortable with raised handle bars and the seat that offers an upright seating position.
Q) Reaction of people when they see this classic motorcycle?
A) Most people have no idea about this bike. They think this is a RD 350. Because that is the only bike they know with twin exhaust. It can get quite frustrating to make them understand that this is a Jawa / Yezdi 350. Mostly I nod and say yes it is a RD 350. Makes my life easier, makes them happier that they know so much.
Q) Do you maintain / repair this motorcycle on your own or is there any mechanic or specialist to take care of?
A) I do most of the stuff in mechanicals myself. I need help with electricals and at times tuning. I take the bike regularly to Mane’s garage on Tilak Road, near Swargate.
Q) Member of any club?
Q) Motorcycles / cars you wish to see parked in your garage?
A) Triumph Tiger 800 XRx (maybe / hopefully / wishfully)
