Exclusivity is expensive. So is cutting-edge technology.
Aprilia’s RSV4 X-GP and Kawasaki’s H2 range possess both. Their price tags and pre-order processes reflect that.
Xtremely Xclusive
Aprilia debuted its ultra-limited X line with the arrival of the RSV4 X in 2019. In its footsteps followed the 2020 Tuono X, 2022 RSV4 X Trenta, and 2024 RSV4 X EX3MA. This year’s RSV4 X-GP isn’t just the latest entry; it also brings the series that much closer to the Noale firm’s MotoGP race machine.
Built on the RSV4 platform, the X-GP earns several features inspired by Aprilia’s RS-GP25 prototype. Its aero package tops that bill. Constructed completely from carbon fiber — in what Aprilia calls a “sandwich structure type” process — the GP-style bodywork is hailed as “extremely light, whilst still maintaining the desired stiffness.”
Integrated into that bodywork is a series of aerodynamic winglets. There are tail wings, leg wings, and cornering wings. There’s a front wing and an underwing. The Italian OEM claims the aero package provides five times the vertical load of the standard RSV4 on the straights, which in its estimation, yields greater stability and precision. The wings also reportedly triple the bike’s load when leaned over, improving grip. Aprilia doesn't specify how fast you have to be going to achieve those levels of downforce, but I suspect it's a speed that's much more likely to be reached by Aprilia's MotoGP riders than the rest of us.
Like all RSV4s, the X-GP still harnesses a 65-degree 1,099 cc V4, but Aprilia engineers prep the powerplant for life on the closed circuit. That includes a higher compression ratio, high-flow racing air filter, race-spec intake trumpets, and a MotoGP replica titanium SC Project exhaust. The payoff is 238 horsepower (at 13,750 rpm) and 96.6 foot-pounds of torque (at 11,750 rpm).
The V4 still resides in a twin-spar aluminum frame, but that tandem is now surrounded by top-shelf race components such as Öhlins suspension (mechanically adjustable FKR fork and TTX shock), Marchesini forged wheels, Pirelli Diablo SBK slicks, and Brembo GP4 MS calipers.
Alongside all that up-spec hardware, Aprilia Racing’s APX software brings WSBK-level electronics to the X-GP. The system allows owners to adjust front-wheel lift, power, traction control, and engine braking for individual gears. Data acquisition also comes by way of a built-in GPS module and Yashi laptop (included with each example).
With only 30 RSV4 X-GPs produced, each unit starts at €90,000 ($105,000) and must be ordered through a dedicated Aprilia webpage. Although, it isn’t the only special-order superbike to make news recently.
Green for go
Last week, Kawasaki opened the order period for the Ninja H2, Ninja H2 Carbon, and Ninja H2R. The limited-production models won’t be available for long, though, with Team Green scheduled to close all H2 orders on October 31, 2025.
Unlike the X-GP, which applies key revisions to Aprilia’s existing RSV4 superbike, the H2 family returns unchanged in 2026. That means the standard model still touts a supercharged 998 cc inline four that produces a claimed 240 horsepower (at 11,500 rpm) and 104.9 foot-pounds (at 11,000 rpm).
Its lightweight trellis frame, single-sided swingarm, Brembo Stylema calipers, advanced rider aids, bi-directional quickshifter, and self-healing paint all help to justify the model’s $32,700 MSRP. Meanwhile, the H2 Carbon, a carbon-clad version of the base package, goes for $36,200.
At the top of the H2 pecking order is the H2R, which cranks the performance up to 11 with its retuned 998 cc I-4 pumping out an eye-watering 322 horsepower (at 14,000 rpm) and 121.5 foot-pounds of torque (at 12,500 rpm). For that reason, the R-spec trim carries a $59,100 price tag and is limited to track use only. Customers interested in adding one of the supercharged superbikes to their stable can submit a request via Kawasaki’s website.
