Overview

Introducing the 2008 AJP PR4 125 Supermoto, a spirited contender in the supermoto category that expertly blends exhilarating performance with nimble handling. AJP, a brand known for its rugged off-road motorcycles, has crafted the PR4 125 to cater to riders seeking a thrilling urban experience without compromising on versatility. With its lightweight build and agile frame, this bike is designed to navigate both the bustling city streets and twisty backroads with ease, making it a perfect choice for both new and experienced riders looking to enter the world of supermotard riding. At the heart of the AJP PR4 125 lies a robust 124cc single-cylinder, four-stroke engine that delivers a commendable 12.47 horsepower at 8500 RPM. This powerplant, coupled with a smooth 5-speed gearbox, ensures that riders enjoy responsive acceleration and a lively ride. The air-cooled engine’s compact dimensions—highlighted by a bore and stroke of 56.5 x 49.5 mm—allow for a lightweight design that contributes to the bike's agile performance. Whether weaving through traffic or tackling a twisty mountain road, the PR4 125’s low weight of just 101 kg (222.7 lbs) and a power-to-weight ratio of 0.1235 HP/kg provide an exhilarating riding experience that’s both engaging and accessible. The AJP PR4 125 Supermoto is equipped with a host of features that enhance its performance and rider comfort. Its steel double-cradle frame with a detachable rear section not only contributes to the bike’s durability but also aids in easy maintenance. The front and rear hydraulic suspension, with a generous stroke of 260mm, absorbs bumps and irregularities in the road, ensuring a smooth ride. The braking system is equally impressive, boasting a 255 mm front disc with a two-piston caliper and a 210 mm rear disc with a four-piston caliper, providing confident stopping power. Additionally, the bike features both electric and kick starters, making it convenient for varying riding conditions. **

Pros

  • Lightweight and Nimble: Weighing just 101 kg, the PR4 125 is easy to maneuver, ideal for both urban commuting and spirited rides on twisty roads.
  • Versatile Performance: The combination of a responsive engine and a well-tuned suspension allows the bike to excel in various riding conditions, from city streets to off-road trails.
  • User-Friendly Features: The inclusion of both electric and kick starters adds convenience and reliability, appealing to riders of all skill levels.

Cons

  • Limited Power for Highway Use: With only 12.47 HP, the PR4 125 may struggle to keep up with faster highway traffic, making it more suited for city and backroad riding.
  • Modest Engine Displacement: The 124cc engine may not appeal to riders looking for more robust power or advanced performance, potentially limiting its market appeal.
  • Height Considerations: With a seat height of 850 mm (33.5 inches), it may pose a challenge for shorter riders, although it is adjustable at its lowest setting.
