4.7/5.0

Looks / Appearance 4.6 / 5.0
Functionality 4.8 / 5.0
Ease of use 4.7 / 5.0

Pros

1. Developed extensively in MotoGP and World Superbike racing, where the performance requirements — durability, feel, and consistency of slide characteristics — are more demanding than any road track environment
2. Anatomically shaped slider geometry provides even-wear distribution across the contact face and optimal contact consistency during cornering, rather than the uneven wear pattern of non-anatomical slider designs
3. Standard fitment on selected Alpinestars leather suits, confirming these are the reference slider specification for the Alpinestars racing suit range

Cons

1. At £69.99, these are positioned at the premium end of the knee slider market — riders on a budget can achieve similar function from the GP Sport Evo at a lower price point
2. Proprietary polymer compound performance is optimised for the asphalt contact characteristics of circuit racing; riders who do a mix of circuit and road riding may find the wear rate higher in certain road surface conditions
3. Strong Velcro fitment, while secure, requires the suit’s Velcro patch to be in good condition; worn Velcro on older suits reduces slider retention reliability

Knee sliders are a consumable part of the track riding experience, and the difference between a well-specified slider and a budget alternative shows up in two ways: the feel of the slide at corner lean, and the consistency of that feel as the slider wears. The Alpinestars GP Pro Knee Slider is developed at the highest level of the sport — MotoGP and World Superbike — where those differences are felt and measured by riders and engineers who know exactly what good slider performance looks like.

The slider is constructed from an exclusive proprietary polymer compound developed through Alpinestars’ racing programme. The compound is formulated to be durable for extended track use while still providing the feedback and feel that experienced riders use to judge their lean angle and contact point during cornering. A slider that is too hard provides insufficient feel; one that is too soft wears too quickly and provides inconsistent feedback as its profile changes. The GP Pro compound hits the balance that MotoGP-level performance demand.

The anatomical shape of the slider is designed for optimal contact between the slider face and the asphalt during cornering lean. Rather than a generic rectangular block, the shaped profile follows the natural geometry of the knee during a lean, distributing contact across the slider face evenly. Even-wear distribution extends the useful life of each slider while maintaining a consistent contact profile from the first lap to the last.

Strong Velcro contacts on the back of the slider provide secure fitment to the Velcro patches on performance leather suits. The GP Pro is standard fitment on selected Alpinestars leather suits, making it the reference replacement specification for those suits.

Who is the Alpinestars GP Pro Knee Sliders aimed at?

The GP Pro Knee Sliders are for track and circuit riders who use a leather riding suit and want knee sliders developed and refined in the demands of MotoGP and World Superbike racing. They suit riders who ride consistently at corner lean and want sliders with consistent feel and even-wear performance across a season of track use.

Specifications:

– Exclusive proprietary polymer compound for durability and feel balance
– Anatomically shaped for optimal asphalt contact and even-wear distribution
– Developed extensively in MotoGP and World Superbike
– Strong Velcro contacts for secure, personalised fitment
– Standard fitment on selected Alpinestars leather suits
– Lightweight and slim profile

The GP Pro Knee Sliders at £69.99 are the racing-grade choice for serious track riders, with MotoGP development behind every element of their design. If you’re cornering hard enough to use them, these are the right sliders to fit.

Our Verdict

The GP Pro Knee Sliders are the racing-grade choice for riders who want MotoGP-developed performance in their knee slider. The proprietary polymer, anatomical shaping, and even-wear characteristics make them a genuinely different proposition from budget sliders, and at £69.99 they’re appropriate for serious track riders who want the specification that professional racing has refined.
