Metric precision meets American robustness in this 1.250" bore silver wheel hub, designed exclusively for metric pattern wheels. Pre-installed studs and included flange nuts make wheel changes a snap, cutting pit time and keeping you competitive. The silver finish not only appeals aesthetically but also dissipates heat effectively, vital for sustained high-speed runs.

• 1.250-inch bore fits standard metric axles with zero play.
• Industry-standard metric studs for universal wheel compatibility.
• Flange nuts provide secure, reusable fastening without stripping.

For karts running European-style components, this hub bridges gaps in availability, ensuring your rear setup performs at peak. It promotes even stud tension, which is crucial for maintaining wheel centering and avoiding vibrations that sap power. Racers in metric-heavy classes like Rotax find it indispensable for consistent stagger adjustments.

The lightweight silver alloy reduces unsprung weight, allowing sharper suspension reactions and better bump absorption on uneven surfaces. Organize your metric toolkit around this hub—its complete kit means no hunting for loose parts. In wet races, the secure mounting prevents loosening, preserving traction where it counts.

Upgrade to this hub and experience the fluidity in rear dynamics; it's like giving your kart a set of grippier shoes. Perfect for teams mixing brands, it standardizes rear fitment without custom work. SKU: BMC7125HI. Metric mastery for faster tracks.
