PIT PRO Trail Dirt Bike 15mm Wheel Spacer Set
The Pit PRO spacer set from Greesp is designed for dirt bikes using a 15mm axle. The spacers feature a 22mm outer diameter and a 15mm inner bore, delivering a compact profile that helps maintain wheel alignment and steering response on varied terrain. This configuration supports a range of bikes in the 50cc to 160cc class, enabling riders to fine-tune track width for stability without compromising fitment. The set’s construction aims to balance durability with light weight for off-road reliability.
For compatibility, verify your bike’s axle size and clearance around the fork, brake caliper, and swingarm. Proper installation ensures even load distribution and reduces the risk of wheel wobble during aggressive throttle and braking. These spacers are suited for riders seeking consistent performance across dirt, mud, and loose terrain, where precise wheel alignment can influence handling and traction.
JFG RACING Front Wheel Hub Spacer
This JFG RACING hub spacer is crafted for dirt bikes and electric Sur Ron S/X models, ensuring a precise front-wheel alignment. The spacer is CNC machined from high-quality aluminum alloy and incorporates an O-ring, improving durability and vibration resistance. An integral lip helps prevent the spacer from detaching from the seal during service, which enhances reliability during tire changes or maintenance. The result is a lighter, more durable alternative to standard spacers, better aligned with the lightweight design principles of Sur Ron and similar bikes.
Key considerations include ensuring the front hub spacer matches your bike’s fork width and hub design. The combination of aluminum strength and a careful lip design supports frequent disassembly and reassembly without excessive wear. If you ride aggressively on rocky or loose terrain, the tighter fit and reduced mass can contribute to steadier steering and quicker throttle response in the front end.
12mm Wheel Axle Spacers Kit
This Greesp kit provides universal 12mm axle spacers with a 12mm inner diameter and a 20mm outer diameter, available in 15mm, 20mm, and 27mm lengths. Its versatility makes it suitable for a wide range of bikes, including Pit Bikes, ATVs, and quads. The kit’s multiple lengths allow riders to tailor spacer thickness for precise wheel alignment, track width, and brake caliper clearance. The robust design aims to minimize play and vibration under demanding riding conditions, contributing to improved stability.
When using these spacers, confirm the axle dimensions and the hub’s bore to ensure a snug, secure fit. Proper spacing helps maintain wheel alignment during cornering and braking, reducing uneven tire wear. This kit is well-suited for riders who frequently swap bikes or who run variations of a single platform across different model years.
15mm Pit Dirt Bike Wheel Spacers
The 15mm spacers from this Pit Dirt Bike line are designed to support front-wheel spacing with a 15mm inner diameter and a 22mm outer diameter. The kit emphasizes straightforward installation for front-wheel alignment, with a focus on reliability across standard dirt-bike setups. Riders can use these spacers to fine-tune track width for better balance, especially when upgrading wheels or adjusting for wider tires. The product package indicates inclusion of spacers suitable for classic SDG and other dirt bike configurations.
Fitment considerations include ensuring the spacers’ inner bore aligns with the axle size and that the exterior clears the brake rotor and caliper. For maintenance, inspect the spacers for signs of wear or corrosion and replace as necessary to maintain consistent alignment and braking performance on rough or variable terrain.
Three 12mm Axle Spacers Set
This three-pack of 12mm axle spacers provides flexibility for multiple bikes or evolving setups. The spacers feature an inner diameter of 12mm and come in lengths of 15mm, 20mm, and 27mm. The kit’s design supports common dirt bike and quad configurations, including Pit Bikes and ATVs, making it a practical choice for riders who frequently adjust spacing to accommodate different tires or hub widths. The variety of lengths helps achieve precise alignment while maintaining structural integrity during off-road riding.
When using a multi-spacer kit, plan the final spacing in advance to ensure even load distribution across the axle and hub assemblies. Regularly check for wear or looseness after hard landings or aggressive braking, and replace spacers if there is any visible damage or deformation that could impact wheel alignment or safety.
Buying Guide
Choosing the right dirt bike wheel spacers involves assessing fitment, material, and intended use. The following considerations help ensure you select spacers that improve stability and handling without compromising safety.
- Size and fitment: Match the inner diameter to your axle or hub bore and verify outer diameter clears brake calipers, forks, and swingarms. Spacers should maintain proper wheel alignment and avoid contact with moving parts.
- Length options: Spacers come in various lengths (commonly 12mm, 15mm, 20mm, 27mm). Choose lengths that achieve your desired track width while preserving steering response and wheel rigidity.
- Material and durability: Aluminum spacers offer light weight and good strength; steel spacers provide higher rigidity and durability in harsh conditions. Consider corrosion resistance for wet or muddy riding.
- Front vs. rear suitability: Front hub spacers influence steering feel and rotor clearance, while axle spacers affect axle alignment and wheel stability. Determine whether you need a front hub spacer, rear spacer, or a universal spacer kit.
- Installation and maintenance: Proper torque and seating are essential. Inspect spacers for wear, burrs, or deformation after significant impacts and replace if needed to prevent wheel misalignment.
- Compatibility with models: Check compatibility with popular frames like XR50, CRF50, Pit PRO, Sur Ron, and other 50cc–160cc dirt bikes to ensure solid fitment across variations.
- Cost-to-value balance: A well-made spacer kit can improve stability and handling, reducing tire wear and improving ride confidence on uneven terrain; evaluate the overall value based on material, size options, and included spacers.
In short, the right spacers help align wheels, expand or tailor track width, and preserve steering feel during aggressive riding. By choosing spacers that match your bike’s axle size, hub design, and the terrain you ride, you can achieve more consistent handling, safer braking, and better overall stability on trails, tracks, and rugged dirt roads.
