This Modified Yamaha RX100 Rocks A 200cc Twin Cylinder Engine

Even with its crazy engine modifications, this RX is built to look as stock as possible.

[UPDATE: Yamaha has confirmed that the RX100 will be coming back to India. Check out the new details in our report]

Since its inception in 1985, the Yamaha RX100 has been a favourite among riders in the 100cc two-stroke category. It has been extensively modified by its owners over the years and is still seen on Indian roads today. This particular one though rocks a more powerful and a rather unique engine.

This RX100, owned and engineered by Mr. Yusuf from Mumbai, has a 200cc parallel twin heart. While Yusuf didn’t mention the exact process of how this engine came together, it certainly looks, to us at least, that he took two 100cc RX100 engines and Frankensteined them together.

The tank has been widened from below in accordance with the size of the twin engine to keep the original retro styling of the bike. Complementing this upgraded engine is a functional twin disc brake setup at the front. The chassis has been rebuilt too, in order to accommodate the larger twin cylinder engine that is dual carbureted and has been tuned by hand. 

The seat is stock and even an original luggage rack has been added to keep the bike looking as if it rolled out from the factory. It even has a twin exhaust system with both exhausts taken from the original. The original spark plugs for the bike have been swapped by the ones from the RD 350. 

Furthermore, the speedometer is also lifted straight from the RXZ. Overall, the bike is a testament to what can be accomplished when old and new come together. Hopefully this will inspire more modern renditions of older vehicles.
