Machined to the dimensions commonly used on 80cc–105cc mini bikes, the assembly includes the axle shaft, a centering spacer, four metal flat washers, and threaded ends sized for lock nuts. A corrosion-resistant surface treatment and hardened steel core provide an extended service life, while compatibility with 6201RS wheel bearings makes it an easy swap during routine maintenance or part upgrades.\u003c\/p\u003e\n\n\u003ch3\u003eWill this axle fit my Monster Mega Moto or Coleman mini bike?\u003c\/h3\u003e\n\u003cp\u003eThe axle is designed as a 255mm rear wheel axle for Monster Mega Moto MM-B80 and MM-B105 models and fits several Coleman mini bike variants such as the Realtree RB100 and RT100, plus oryxearth 105cc kids dirt bikes. Confirm your bike uses 6201RS bearings and a 255mm axle length before purchasing. If your frame or hub uses different bearings or lengths, measure the current axle to ensure a proper match.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eIntended models: MM-B80, MM-B105, RB100, RT100, oryxearth 105cc\u003c\/li\u003e\n  \u003cli\u003eLength: 255mm standard rear axle shaft\u003c\/li\u003e\n  \u003cli\u003eBearing compatibility: fits 6201RS wheel bearings\u003c\/li\u003e\n  \u003cli\u003eThreaded ends: accept lock nuts for secure fastening\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does the construction affect durability and performance?\u003c\/h3\u003e\n\u003cp\u003eThe axle is forged from high-strength, hardened steel and precision-machined for straightness and accurate fits. A corrosion-resistant finish resists rust and environmental wear, which helps maintain smooth wheel rotation over time. Precision machining reduces wobble, protects bearings, and distributes loads evenly to prevent premature failure.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eHardened steel core for high load capacity\u003c\/li\u003e\n  \u003cli\u003eCorrosion-resistant coating to extend lifespan\u003c\/li\u003e\n  \u003cli\u003ePrecision machining for accurate wheel alignment\u003c\/li\u003e\n  \u003cli\u003eThreaded ends for secure lock-nut retention\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat parts are included and how do they improve installation?\u003c\/h3\u003e\n\u003cp\u003eThe kit arrives complete with a spacer and four flat metal washers alongside the axle shaft, so you don’t have to hunt for matching hardware. The spacer centers the wheel within the frame, while the washers distribute pressure across the bearing seals and hub faces to reduce stress points. Threaded ends accept lock nuts that keep the assembly tight under vibration and riding loads.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eOne 255mm rear axle shaft, pre-machined\u003c\/li\u003e\n  \u003cli\u003eOne centering spacer to position the wheel\u003c\/li\u003e\n  \u003cli\u003eFour metal flat washers to equalize load on bearings\u003c\/li\u003e\n  \u003cli\u003eThreaded axle ends ready for lock nut installation\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow simple is installation and maintenance?\u003c\/h3\u003e\n\u003cp\u003eInstallation is straightforward for anyone comfortable with basic mini bike maintenance: remove the wheel, replace the axle and spacer, add washers, and torque the lock nuts to spec. The axle’s standard sizing and bearing compatibility minimize the need for additional parts. Routine checks of torque and signs of corrosion will keep the axle performing reliably for seasons of use.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eStraight swap in most MM-B80\/MM-B105 and RB100\/RT100 setups\u003c\/li\u003e\n  \u003cli\u003eUses common 6201RS bearings—no specialty parts required\u003c\/li\u003e\n  \u003cli\u003eThreaded ends simplify locking and periodic retorque\u003c\/li\u003e\n  \u003cli\u003eLow-touch maintenance: inspect for rust and retorque as needed\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: This axle assembly is aimed at mini bike owners, mechanics, and hobbyists who need a rugged replacement rear axle for 80cc–105cc models from Monster Mega Moto, Coleman, and oryxearth.
