Yamaha Rdx 135
The Yamaha RDX 135 is not a verified or widely documented model in Yamaha's official global lineup. It is possible this refers to a regional variant, a rebadged model, or may be confused with the Yamaha RX135 (a 2-stroke 135cc commuter popular in India and Southeast Asia in the 1980s–2000s) or the Yamaha RXZ 135. The RX-series bikes were notable for their sporty 2-stroke performance in the budget commuter segment across Asian markets.

What Buyers Should Know
2-Stroke Power Plant
The RDX 135 uses a 2-stroke engine delivering punchy performance beyond its displacement, but requires regular premix oil maintenance and reed valve inspections to avoid costly top-end damage.
Watch the Powervalve
The YPVS (Yamaha Power Valve System) is a key performance feature but is a common problem area — carbon buildup can seize the valve, causing flat power delivery and expensive repairs if ignored.
Strong Resale Demand
Well-maintained RDX 135s hold their value well in Southeast Asian markets due to strong enthusiast demand, but modified or neglected examples can be significantly harder to sell at a fair price.
