ProTaper Micro Handlebar Kit

The ProTaper Micro Handlebar Kit is an innovative, purpose-designed handlebar and control system engineered specifically for youth riders and mini motocross machines ranging from 50cc to 85cc. Stock mini-bike handlebars utilize adult-sized 7/8-inch grip diameters that force young riders with smaller hands to over-grip, leading to rapid hand fatigue, diminished throttle modulation, and compromised machine control. The Micro Handlebar Kit solves this by utilizing an advanced tapered design where the grip and throttle control zones are reduced to a smaller diameter, matching the natural ergonomics of youth hands.

Constructed from ProTaper's exclusive 2000-series T6 aluminum alloy, the Micro bar maintains standard 7/8-inch (22.2mm) diameter at the central triple-clamp mounting area, allowing it to drop directly into standard mini-bike bar clamps without expensive adapters. The bar then transitions to a reduced diameter at the grip sections. The kit includes a custom two-piece multi-cam throttle tube with interchangeable throttle reels to match various 2-stroke and 4-stroke mini bike cable configurations, as well as ultra-soft micro-diameter half-waffle grips. On the track, young racers gain immediate confidence through a more secure grasp, enhanced brake and clutch lever reach, and smoother throttle execution over jumps and through corners.

Step-by-Step Installation & Safety Protocols

Installation involves removing the stock mini handlebar, throttle assembly, and grips. Install the Micro handlebar into the OEM 7/8-inch clamps, aligning the central positioning marks, and torque the clamp bolts evenly to 15-18 Nm. Select the appropriate throttle cam reel included in the kit that matches your bike's throttle cable barrel. Assemble the throttle tube onto the bar with a light application of dry PTFE lubricant (never use heavy grease which attracts dirt), ensuring free return when released. Install the supplied micro-diameter grips using quality grip glue, and mount all levers and kill switches.

Maintenance & Inspection Routine

Maintenance requires inspecting the throttle tube for smooth rotation before every moto, cleaning dirt out of the throttle housing, and checking grip wear. Periodically verify clamp torque. Replace the handlebar immediately if bent during a crash.
