The Yamaha RX100 is a 98cc two-stroke single cylinder aircooled motorcycle. It was M/s Escorts Limited's "Bread and Butter" model for close to 12 years between 1985 and 1996. The only changes in its 11 year production history were the pinstriping and an upgrade to a 12 volt electrical system.

History Escorts Limited partnered with Yamaha Motor Corp. in 1983 to launch the "Rajdoot "Rajdoot 350" 350" a license produced Yamaha RD350B. Another player in the Indian two wheeler market was IND-SUZUKI (TVS (TVS Motor Company today) which, as the name suggests, joined hands with Suzuki to launch the 8.25 bhp (6.15 kW) IND-SUZUKI AX100 in 1984. Taking a page out ou t of TVS-Suzuki's book, Escorts soon realized that sales success lay in smaller displacement b ikes that are more economically priced and cheaper to run. Thus launched the YAMAHA RX100 in late 1985 (Workshop Manual is dated May 1985). The bike b ike was originally available in Cherry-Red, Flamboyant-Blue(Peacock blue-green) Black and Silver. The first lot bikes (1985-1987) were CKDs and were simply assembled in India. The gearbox covering just above the gear shift lever had the words w ords "MADE IN JAPAN" embossed on it & the eng ines were 110CC & weren't 98CC.
Incidentally, the speedometer casing in the early bikes had the lettering "RAJDOOT" on them as did the speedometer dial. These older meters were manufactured by Yenka y. As opposed to later ones made by Pricol which had ESCORTS and later YAMAHA casings and dials. Few parts like the two-stroke oil pu mp cover which is circular, had "Rajdoot" embossed instead of the expected YAMAHA or ESCORTS. This gives the idea that maybe, Escorts wanted to launch the bike as the "Rajdoot 100" in the same league with the Rajdoot 350. The only major change that the bike underwent was that it was w as upgraded from a 6V electrical system to a 1 2V system. Apart from that, the pinstriping was changed two times. So there are three different decal types in all. The bike is legendary in every possible way. Two other colors (Wine red and Metallic blue) were also introduced, but bu t the bike stayed the way it was for its 11 year history.
Performance

The gear ratios and torque curve are such that a well tuned bike with rider and pillion can do as low as 10 km/h in 4th gear without engine knocking. knocking. 1985 rx100 excutive and in production for function
Successors The bike's production run lasted from Nov 1985 – Mar 1996. Various modifications like expansion chambers, drum brakes and 5th gear. The model was followed by the 11.8 bhp 132 cc RXG, which had a faulty ignition system, which was replaced by the company at no cost. Next came the RX135 RX135,, which was essentially a rebadged RXG. The RXZ was launched with a sportier headlamp fairing.Finally, in the year 2000-2001 were launched the 14 bhp (10 kW) RX135 and the RXZ (Both 5-speed with a catalytic converter silencer). These met with lukewarm resp silencer, sporting a fuel gauge and speedometer with w ith white dials which was sold very briefly in 2003. The Yamaha RX-135 (also popularly known under the name RX-King or RX-K in Southeast Asia, Asia, especially Indonesia Indonesia)) is a 2-stroke motorcycle produced by Yamaha since the 1980s, now made by the Indian subsidiary India Yamaha Motor .
[edit edit]] The RX-135 in India
The RX-135 was released around the end of the 1990s and in select India cities, you could get a factory-shipped RX-135 till August 2005. There were 2 versions of this bike sold in India - the 4 speed and the 5 speed. Apart from the difference in the transmission, the bikes differed in the carburettor design as well. The engine was the only o nly 2-stroke bike you could get in the Indian market till mid-2000s, selling for a little while longer than the more sedate TVS Suzuki Samurai. Delivering 14 brake horsepower (10 kW), a well maintained vehicle could give you up to 51 kmpl, making it amongst the best mileage-to-power ratio in all India bikes. Add to that the sheer quality of Yamaha parts. Top speeds claimed approach nearly 120 km/h. On the streets the main competition for this bike came from Kawasaki Bajaj's KB100 and KB1 25, TVS Suzuki's Shogun and Samurai and most importantly an array of economical to run 4 stroke 100 cc bikes.
