There is a science to building high-performance engines and the GSX-R125’s DOHC engine is a perfect example of how to make a lot of power out of a very efficient and compact power plant. This power combines with strong torque and exceptional fuel economy, to create an engine worthy of the GSX-R marque.
Motorcycle News took six of the best sporty 125s for a two-day thrash to find the perfect L-plate thriller. The GSX-R125 topped MCN's speed chart with a speedometer reading of 72.75mph and also topped their track day table making it the most fun 125cc bike to ride.
To make the best use of every ounce of power from the GSX-R125’s class leading engine, the bikes sporty bodywork is also extremely aerodynamically efficient to reduce drag and maximise efficient speed. This design is the result of extensive wind tunnel development, and the sleek bodywork also enhances the GSX-R125’s easy handling character. Furthermore, it also has the smallest projected frontal area in the 125cc class helping to achieve that best in class acceleration and supports high levels of fuel efficiency.
