The RX 135 5-Speed is still a sort after bike in second hand market by many yamaha lovers. The RX 135 5-Speed was having same 132cc 2-stroke engine as RXG/ RX 135 4-Speed tweaked to produce 14 Bhp at 7500 Rpm.
The bike used to have a low resonating exhaust pipe because of strict pollution law resulting a very subdued sound.
