Comparison: RX 100 vs. Modern Commuters

Feature	Yamaha RX 100	Modern 100cc Bikes (e.g., Splendor+)
Engine Type	2-stroke	4-stroke
Power Output	11 PS	7–8 PS
Mileage	35–45 km/l	60–70 km/l
Top Speed	~100 km/h	~90 km/h
Emission Norms	Non-compliant	BS6

While modern bikes are cleaner and more fuel-efficient, none can match the RX 100's raw power and thrill.

Why Was It Discontinued?

The RX 100 couldn’t meet the emission standards introduced in the mid-90s. As India moved toward more fuel-efficient and eco-friendly four-stroke engines, two-stroke bikes like the RX 100 were phased out.

Its successors like the RXG, RX 135, and RX-Z attempted to carry the legacy, but none could match the original’s legendary status.

Legacy and Cultural Impact

• Featured in movies, TV shows, and music videos

• Considered a status symbol among youth in the 80s–90s

• Popular with police, stunt riders, and even racers

• Many models are now collector’s items worth ₹1 lakh or more if restored

Even today, RX 100 fan clubs and forums are active across India, keeping the spirit alive.

2025 Relaunch Rumors – Fact or Fiction?

In recent years, rumors have surfaced about Yamaha relaunching the RX 100 with a BS6-compliant engine. However:

• Yamaha has confirmed interest in reviving the RX brand name

• A true two-stroke RX 100 comeback is highly unlikely due to emission laws

• A 4-stroke, retro-inspired RX may be introduced—but it won’t be the same firecracker the original was

So, while the RX name might return, the original’s soul remains a one-time masterpiece.
