Ultimax Pro Drive Belt 138-4400U4

• Ultimax 3 has evolved into Ultimax Pro
• Belt features a thicker cross section so more surface area contacts the clutch; this means less slippage over a broader speed range for quicker acceleration
• New cog design dissipates heat and aids flexibility
• Cooler-running belts mean better performance and longer-lasting belts
• Run cool, run long, run fast with Ultimax Pro
• Top-cog design
