YAMAHA RX100 Power History with Facts | RX 100 Restoration Modification | DA MODS | ENGINEER SINGH

Following the dismal sales of the Rajdoot 350, Yamaha needed to make a comeback product, and the recent success of Suzuki's AX 100 demonstrated the potential of small-capacity motorbikes in India. In November 1985, Yamaha released the RX 100 to widespread acclaim. The appeal came largely from the surprise that its 100 cc (6.1 cu in) engine could deliver as much power as it did. Race conductors and authorities often double checked the engine by opening the engine block to make sure it was actually 100 cc. The RX 100 was quickly adopted by racers who recognized its potential in drag racing. Various modifications such as expansion chambers, porting, engine tuning, sprocketing and changing wheel sizes (16, 17 and 18 in (410, 430 and 460 mm)) became fairly common. Furthermore, upgrades such as bigger carburetors, air filters, quicker throttle, disc brakes, an additional 5th gear, race pistons, racing CDI systems, upgraded tires and suspension dampening were released, allowing riders to customize their bikes. A 1989 model of the Yamaha RX 100 Tuned RX 100's have completed the so-called standing start quarter-mile in about 14 seconds – a respectable figure, considering the much larger BMW-S1000RR 4-Cylinder 1,000 cc (61 cu in) bike can cover one-quarter mile (0.4 km) in 10.2 seconds. The bikes was manufactured between 1985 and 1987 and were knock-down kits, (CKD), from Japan and were assembled in India. Only the model produced in Japan had disc brakes. The bikes were sold in Peacock Blue, Cherry Red and Metallic Black stock colors. The only major changes that the bike underwent was upgrading from a 6-volt electrical system to a 12-volt system with the addition of a CDI (capacitor discharge ignition) system for improved ignition and timing. The bike's production lasted from November 1985 – March 1996. Stricter emission laws and regulations in India made the continuing production of the RX 100 impossible. The CKD model was then followed by the 11.8 bhp (8.8 kW), 132 cc (8.1 cu in) RXG, with a taller primary and secondary reduction. It had the same lightened flywheel from the RX 100 that causes a jerky ride. It was replaced by the manufacturer by a heavier flywheel the following year. Then came the RX-Z in 1997, with a new chassis and a shorter wheelbase with the same primary reduction ratio as the RX100 but with a taller final reduction. The RX-Z was launched with sportier bodywork and produced 12 bhp (8.9 kW) at 6,500rpm. Following the RX-Z, the RX135 was launched in 1998 with the same engine as the RXZ but using the same chassis as the RX 100 or RXG. The RX135 saw a moderate success due to its refined power output and better fuel economy. Finally, in 2000 Yamaha launched the 14 bhp (10 kW), 7,500rpm RX135 5 speed with a catalytic converter silencer. It failed in the market due to its poor fuel economy and was discontinued after two years. The RX 135 was later recognized as the quickest RX and has a cult status due to its rarity. A 5-speed variant of the RX-Z with front disc brakes also had a limited release in 2001 at a premium price tag. The final variant was a 4-speed RX 135 with a catalytic converter silencer, sporting a fuel gauge and speedometer with white dials which was sold very briefly from 2003 to 2005.
