The new trellis-frame and rebound adjustable back mono-shock add to the razor-sharp handling of the RFZ and features like front and rear disc brakes round off the package.
The 140S is the tallest pit bike in Big Boy’s range, featuring an 860mm seat height and 19”/16” wheels making it the perfect model for medium sized riders, male or female, beginner or experienced.
