Your most-used control, made effortless. ZeroDrag eliminates gritty throttle feel and friction for a lighter, smoother, near-maintenance-free throttle — even when you're weighting the bars.
Sealed cartridge bearings · installs inside the bar · bar ends included · fits most trials & enduro bars
Friction eliminated Sealed cartridge bearings carry your hand load directly for a smooth action under real riding load.
Sealed & protected Fully enclosed inside the bar, shielded from water, grit and impact — little or no maintenance.
Works with bar ends Crashes hit the included bar ends, not your grips or the bearing system.
Smoother, ride after ride Consistent throttle feel that doesn't fade back to gritty over time.
How ZeroDrag is different
Many kits use a single bearing on the outside of the bar, exposed to impact — if it bends, friction spikes. They also only support the very end of the bar, so they feel smooth on a stand but drag returns once your weight is on the bars.
Others use open bearings inside the bar that rust and wear quickly. ZeroDrag uses sealed cartridge bearings fully inside the bar, supporting the throttle where it matters and carrying your hand load properly — smooth under pressure, protected from weather and impact.
Fitment
Fits most trials & enduro handlebars with an inner diameter of 13.8–14.7 mm — Renthal, Astra, S3, Beta, Sherco, GasGas, KTM, Husqvarna, TRS, Vertigo and more. Compatible with throttle tubes that aren't fully open-ended.
Some motocross bars (e.g. ProTaper) have an inner diameter under 13.8 mm and won't fit — there isn't enough room for the bearings.
Installation
A purpose-built installation tool makes setup quick and precise and is strongly recommended (one tool covers multiple bikes). Installation guide →
