Harsire Dirt Bike Training Wheels for PW50, CRF50 & MX125 — 49–50cc Universal Fit, Adjustable Height

Harsire dirt bike training wheels attach to 49cc–50cc kids' off-road motorcycles to give young riders added balance and confidence while they learn.

These stabilization wheels are built for popular small dirt bikes — including Yamaha PW50/TTR50, Honda CRF50/XR50/Z50, and various Razor, SSR and Suzuki junior models — and come with corrosion-resistant hardware, wear-resistant tires, and a ten-year after-sales guarantee. The kit is designed for quick assembly and adjustable ride height so parents can tailor stability to the rider's skill level and the trail conditions.

How do these training wheels improve a child's learning experience?

The Harsire stabilizers reduce the chance of tipping while children build balance, throttle control and confidence. By providing lateral support, they let beginners focus on steering and throttle without constant fear of falling.

• Adjustable height lets you raise or lower support as skills progress.
• Wide, wear-resistant tires increase grip on dirt and gravel.
• Stainless steel axle and clamps resist rust for outdoor use.

Will these fit my PW50, CRF50 or Razor MX125?

The kit was made for a broad range of 49cc–50cc kids' motorcycles; compatibility includes Yamaha PW50/TTR50 series, Honda CRF50/XR50/Z50, Razor MX125/MX350/MX400, SSR and Suzuki junior models. Confirm your specific frame and axle dimensions before ordering to ensure a proper fit.

• Designed for common junior dirt bike axle and frame mounts.
• Check model fit list or measure axle spacing if unsure.
• Customer service can help verify compatibility before purchase.

How long does installation take and what tools are needed?

Most installations take about ten minutes with the included instructions; basic hand tools like wrenches and pliers are typically all that’s required. An illustrated guide in the box and online video tutorials make the process straightforward for parents or guardians.

• Step-by-step paper instructions included in the package.
• Common tools: wrench set, adjustable pliers, and socket set.
• Instructions cover recommended clamp adjustment and safety tips.

Are there safety or maintenance notes I should know?

To keep training sessions safe, limit the bike's speed and periodically check fasteners, tire wear, and axle condition. The kit includes design features that intentionally leave a small gap near the washer to improve balance over uneven terrain.

• Recommended learning speed limit: 6 MPH (10 km/h) maximum.
• Occasional tightening of bolts and inspection of tires advised.
• If extra mounting clamp stability is desired, carefully bend the extended arm back slightly with pliers after installation.

Who is this for? Harsire training wheels are intended for parents and guardians teaching children to ride 49cc–50cc off-road motorcycles who want a durable, adjustable stabilizer kit. They suit beginners who need extra balance support, bike rental workshops, and family riders looking to make first-ride experiences safer and more encouraging. If you want a quick-install, corrosion-resistant solution backed by a long after-sales warranty, this kit is built for that purpose.
