Fits Ktm X-BOW GT-XR (2023-2026)

Brake pad compound

Street: quiet, low-dust, strong cold bite for road driving. Sport: higher temperature range and more bite for fast road and occasional track. Racing: maximum fade resistance for sustained track use (noisier and dustier cold). Match the pad to how hard you actually brake.

Disc size

Caliper grade

Hollow is the standard caliper: a lighter hollow-body forged caliper with a dust cover and a 5-year warranty. Hollow Racing drops the dust cover for sustained high-temperature use (rated to 1000°C, 2-year warranty) — the track-grade choice.

Caliper colour

Painted colours are included. Polished-forged finishes are mirror-polished forged calipers (Titanium, Gold, Silver); candy colours are a deep, mirror-reflection paint. Both are premium upgrades — fuller detail further down the page.

Disc style

Drilled discs (cross-drilled holes) vent gas and water and look aggressive; slotted discs (surface grooves) wipe the pad face clean and resist fade under sustained hard use. Same price — choose on looks or how you drive.

Centre bell

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. Standard anodized is included; a two-tone bell adds an anodized accent ring in your choice of colour; titanium is the lightest, forged option.

Carbon-ceramic rotor

Carbon-ceramic rotors are a special-order track upgrade: far lighter than steel, fade-resistant at extreme temperatures and extremely long-lived. The price follows the disc size you choose above. The standard two-piece steel rotor is included.

XYZ Racing Hollow Front Brake Kit — Ktm X-BOW GT-XR (2023-2026) — 400 mm
400 mm

With near-500bhp and active aerodynamics generating over a tonne of downforce channelled through a carbon monocoque that tips the scales well under a tonne, the KTM X-BOW GT-XR arrives at braking zones carrying a momentum that exposes marginal front-end hardware within a handful of hard laps. The front-axle loading during high-speed stops on this car is in a different category from conventional road-registered sports cars, and the heat cycles that follow are correspondingly brutal. The XYZ Racing front big brake kit for the 2023-2026 GT-XR is engineered for precisely that operating environment.

Three pad compounds reflect how GT-XR owners actually use the car. Road registration is the norm; track use is the point. That compound spread covers the full range without requiring a parts swap between the motorway drive to the circuit gate and the outlap.

What this brake kit does for your 2023-2026 Ktm X-BOW GT-XR

The two-piece floating disc draws cooling air through the disc body as the wheel turns, managing the thermal load that accumulates during the repeated hard stops the GT-XR’s performance envelope and the X-BOW platform’s low weight make routine. Where a conventional vented rotor holds heat in the iron, the hollow-vane design moves it out, keeping pedal feel consistent through a session rather than allowing it to degrade as disc temperatures climb. The floating bell lets the rotor expand evenly under load, the lighter rotating assembly trims unsprung mass on a chassis acutely sensitive to it, and braided lines firm the pedal.

Switching to the Racing compound unlocks the bite threshold that matches what the GT-XR’s aerodynamic front-end load actually allows: sharp, high-peak deceleration the carbon chassis and front suspension geometry absorb cleanly. Street is the quiet, low-dust default for road use. Sport adds bite and a wider heat range for mixed use. You select the compound when you order.

About the front big brake kit

The kit pairs a hollow-body forged caliper as standard with a two-piece floating disc whose vane geometry creates a more active airflow path through the disc body under rotation, drawing thermal energy away from the friction surface before it saturates the iron. On the X-BOW platform, where the lightweight carbon structure and short wheelbase concentrate braking forces rather than absorbing them through chassis compliance, that thermal management is material rather than marginal. Discs are offered drilled or slotted at the same price, and centre bell upgrades come as two-tone anodizing in five colours, or titanium, selectable at checkout.

Included painted caliper colours are Red, Yellow, Gold, Black and Anodized Black at no extra cost. A Custom Color in any Pantone is £150. Premium polished-forged finishes cover Titanium, Polished Gold and Polished Silver, with a premium candy range of Candy Teal, Candy Blue, Candy Red and Candy Orange, fitting on a car as visually considered as the GT-XR, where brake hardware is part of the presentation. For sustained circuit duty, the optional Hollow Racing caliper deletes the dust cover, is rated to 1000C and carries a two-year warranty.

Fitment for the Ktm X-BOW GT-XR (2023-2026)

This front big brake kit is confirmed for the KTM X-BOW GT-XR across the full 2023 to 2026 model year span. The GT-XR’s carbon monocoque construction and front suspension architecture place specific clearance and hub requirements on uprated brake hardware. Use the model year and variant selectors when you order to confirm the correct specification. No trim-level splits apply within this production window.

Choosing your spec

Every kit is built to order around the choices you make above. Here is what each option actually changes, so you can spec yours with confidence.

Brake pads — Street, Sport or Racing

Every kit ships with a full set of high-performance pads; the compound is your call.

Street is the right default for fast-road driving — a strong, progressive cold bite with low noise, low dust and long disc life. Sport raises the working temperature and adds bite and fade resistance for hard road use and the occasional track day, while still behaving on a cold morning. Racing is a track compound built for sustained abuse: huge fade resistance and bite once heat is in it, at the cost of more noise and dust when cold. Match the pad to how hard you actually use the brakes — there is no benefit to a race pad that never gets up to temperature.

Caliper grade — Hollow vs Hollow Racing

Hollow is the standard caliper on every kit: a hollow-body forged caliper, lighter than a solid one, fitted with a dust cover and backed by a 5-year oil-leak warranty. For most fast-road and spirited track use it is all the caliper you need.

Hollow Racing is the track-grade upgrade. It runs the same hollow body but without a dust cover (so there is nothing to melt at sustained high temperature), uses a twin-metal piston that isolates heat travelling from the disc to the oil seal, and is rated to 1000°C. Available 286–380mm (front). Warranty is 2 years on oil leaks and 10 years on appearance. Built for professional racing and repeated track days.

Caliper colour & finish

Painted colours (Red, Yellow, Gold, Black, Anodized Black) are included at no cost. Want an exact match to your car? Custom Color (+£150) paints the calipers to any Pantone code you supply (15–20 day lead time).

Polished Forged finishes are the flagship: a forged caliper given a mirror-polished surface treatment that shifts colour with the viewing angle. Beyond the looks, the polished surface dissipates heat better, resists rust and stands up to the weather. Choose Titanium (neochrome, +£350), Polished Gold (+£300) or Polished Silver (+£250). They look their best paired with a titanium centre bell. Care: clean only with a dilute neutral cleaner or water.

Candy colours (+£200) use a deep candy-paint and polishing process for a mirror-reflection, boutique finish — pick Teal, Blue, Red or Orange (shown below right).

Centre bells

The centre bell is the CNC-machined aluminium hat that joins the disc to the hub. The standard anodized centre bell is included. The Two-tone bell (+£200) adds an anodized accent ring — choose Red, Yellow, Orange, Purple or Silver right here at checkout. The Titanium centre bell (+£500) is a forged titanium bell (bolts not included) that finishes off the polished-forged look.
