From "I'm Too Scared" to Riding Solo — Kids Build Real Confidence on Their First Dirt Bike. When kids tip over on day one, most give up. These heavy duty dirt bike training wheels keep the bike stable so beginners can focus on learning throttle and steering — not on falling. Compatible with Razor MX125/MX350/MX400,Yamaha PW50/TTR50,Honda CRF50,FRP FX40 MB40 GMB100; and most kids dirt bikes with 5.9"–10.6" ground clearance. Safety gear, reflective vest, and bell included at no cost.
Universal Fit Made Possible — M8 and M6 Mounting Bolts Both Included, No Extra Hardware Needed. The most common reason training wheels don't fit is the wrong bolt size. These universal dirt bike training wheels include both M8×5.5cm and M6×5.5cm mounting bolts, so most bikes bolt on without any extra trips to the hardware store. The center steel axle is raised to 4.7" — wider than standard — giving a compatible range of 5.9" to 10.6" ground clearance across most 49cc and 50cc models. If it still doesn't fit your bike, contact us and we'll make it right within 24 hours at no cost to you.
4PR Reinforced Tires + 33.1" Alloy Steel Axle — Handles Dirt, Gravel, and Grass Without Bending or Going Flat. Most training wheels use single-layer tires that split after a few rough rides. These motorcycle training wheels use 2.50-4, 4-ply (4PR) reinforced tires — four layers of construction that hold up on uneven terrain without flattening or cracking. The 33.1" precision alloy steel axle resists deformation from impacts and bumps, so the wheels stay stable no matter how hard your kid rides. Built to last the full learning journey, not just the first few sessions.
Quick Installation with Step-by-Step Video Guide on the Product Page — Two Metal Wrenches Included. All mounting hardware is included — no separate purchases needed. A full installation video is available on the product page to walk you through every bracket and bolt. Most parents complete setup in under 10 minutes. One step that makes a big difference: after sliding the wheels onto the axle, use pliers to bend the cotter pins outward — this locks the wheels securely and prevents them from loosening during rides. Takes 30 seconds and keeps everything in place.
