Get the technical details on speed, safety features, and the Impulse Moto delivery process to ensure the XR-125 is the perfect fit for your young rider.
What is the difference between the XR-125 semi-automatic and manual transmission?
The main difference is how you operate the clutch.
- Semi-Automatic: You still shift through gears using your foot pedal, but there is no hand clutch lever on the handlebars. An automatic clutch handles the engagement for you whenever you shift or stop, making it virtually impossible to stall. This version is ideal for beginners focusing on steering and balance without worrying about stalling.
- Manual Transmission: Features a traditional hand clutch lever on the handlebar. The rider must manually pull the clutch lever to disengage power when shifting gears or stopping. This version gives experienced riders total control over power delivery and acceleration.
What age group and height is the Coolster XR-125 best suited for?
The Coolster XR-125 dirt bike features a 30-inch seat height and 14 inch front wheels and 12 inch rear wheels, making it a mid-size dirt bike designed for teens and adult riders ages 13 and up. Typically riders around 5 foot 5 inches and taller.
Does the Coolster XR-125 have an electric start or kick start?
The XR-125 is equipped with a traditional kick-start system powered by a CDI ignition. Most teens ages 13 and up have the leg strength and weight required to kick-start the 125cc 4-stroke engine once proper technique is learned.
Is the Coolster XR-125 good for a beginner rider?
The XR-125 features 2 transmission options: 4-speed semi-automatic or 4-speed manual transmission with a hand clutch.
