The kit contains six popular sleeve thicknesses to cover most adjustments, all with a 15mm inner bore to slide over standard 15mm axles used on XR50, CRF50 and similar models. These steel bushings are built to resist wear and keep wheel alignment stable under load.\u003c\/p\u003e\n\n\u003ch3\u003eWhich sizes are included and why do they matter?\u003c\/h3\u003e\n\u003cp\u003eThis set bundles six thicknesses—5mm, 10mm, 20mm, 25mm, 30mm and 35mm—totaling 11 pieces to cover left\/right combinations and quick replacements. Using the right spacer thickness prevents axle binding, avoids improper bearing loads, and preserves correct chain and brake alignment.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003e11 total bushings for spare and paired use\u003c\/li\u003e\n  \u003cli\u003e15mm inner diameter to fit standard pit\/mini bike axles\u003c\/li\u003e\n  \u003cli\u003eMultiple thicknesses let you dial in wheel offset and clearance\u003c\/li\u003e\n  \u003cli\u003eHelps maintain correct brake and sprocket alignment\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eHow does material and machining affect performance?\u003c\/h3\u003e\n\u003cp\u003eThese bushings are machined from high-grade steel for toughness and long service life. Steel offers strong wear resistance and better heat dissipation than softer metals, so spacers keep their shape under pressure and temperature cycles encountered on the trail or track.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003ePrecision machining for consistent diameter and concentricity\u003c\/li\u003e\n  \u003cli\u003eSteel construction resists deformation under load\u003c\/li\u003e\n  \u003cli\u003eImproved thermal conductivity reduces heat buildup at the hub\u003c\/li\u003e\n  \u003cli\u003eFinish prevents premature wear of axle and bearing surfaces\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat installation checks should I do before fitting these spacers?\u003c\/h3\u003e\n\u003cp\u003eMeasuring the existing sleeve and axle is essential—an incorrect spacer thickness or bore fit can damage bearings, forks, or the wheel hub. Verify the axle diameter is 15mm and confirm the required spacer thickness by measuring brake rotor to swingarm clearance and hub shoulder distances before installation.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eConfirm axle outer diameter is 15mm before use\u003c\/li\u003e\n  \u003cli\u003eMeasure current sleeve length and hub spacing for correct selection\u003c\/li\u003e\n  \u003cli\u003eInstall one side, torque axle to spec, then recheck alignment\u003c\/li\u003e\n  \u003cli\u003eIf unsure, consult a mechanic or contact GOFIRA support\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWill these spacers work with my bike model?\u003c\/h3\u003e\n\u003cp\u003eThe kit is tailored for small-displacement off-road bikes and many imported mini bikes that use a 15mm front or rear axle. Common fits include XR50 and CRF50-style pit bikes and 50–160cc mini\/dirt bikes, but compatibility depends on axle specification and hub geometry, so measure before buying.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eDesigned for most 15mm-axle pit and mini bikes (50–160cc)\u003c\/li\u003e\n  \u003cli\u003eUseful as a universal spare set for multiple bikes in a garage\u003c\/li\u003e\n  \u003cli\u003eNot for axles with different inner diameters or proprietary spacers\u003c\/li\u003e\n  \u003cli\u003eContact GOFIRA for fitment questions prior to purchase\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003eWho is this for: Riders, mechanics, and weekend wrenchers who need a reliable assortment of axle spacers for mini and pit bikes.
