Wimmer KTM X Bow Trio






When the various KTM X-Bow variants leave the factory, they’re so good that tuners rarely tinker with them. However, the specialists at German tuner Wimmer have decided to thoroughly upgrade three different KTM X-Bows and all told, the trio now deliver over 1300 hp!
First off, Wimmer started with the KTM X-Bow GT (featuring a fixed windscreen). Typically, the X-Bow GT delivers 285 hp and 420 Nm of torque. However, thanks to the fitment of a modified turbocharger, an optimised high-compression pump, new air induction system, a Wimmer exhaust and some serious ECU tuning, the car now delivers a biblical 485 hp and 520 Nm of torque. When combined with an overall weight of just 850 kg, Wimmer claims its X-Bow GT will reach 100 km/h in well under 4 seconds and a top speed of 255 km/h (160 mph).

The need for speed bug has hit Wimmer RS that has just presented three new performance tunes for the KTM X-Bow named GT, R and RR.
With the GT package, the KTM's Audi-sourced 2.0-liter turbo'd four gains a whopping 200PS (197hp) over the stock unit boosting output from 285PS (281hp) and 420Nm to 485PS (478hp) and 520Nm, dropping the power-to-weight ratio to an amazing 1.75 kg per horsepower.
Wimmer says the GT can hit 100km/h (62mph) in well below 4.0 seconds and top out at 257km/h (160mph). There are also changes to the aerodynamics, ESP, ABS and suspension, with the price for this version set at €130,000 (~US$162,000).
Next is the €120,000 (~US$150,000) R tune that has 455PS (449hp) and 400Nm allowing for a top speed of 248km/h (154mph), with Wimmer offering a suspension tune and several other options such as a big rear wing.
The third member of Wimmer's X-Bow family is the non-street legal €110,000 (~US$137,000) RR made exclusively for the track. It has 370PS (365hp) and a raft of other upgrades for the chassis and aerodynamics.
We’re referring to everything from the GT to the R and carbon fiber crazy RR, with the first costing €130,000 after German tuner Wimmer RST works its magic on it. Let’s start with the wildest tune job of this extreme KTM crossbow trio, shall we?
Wimmer’s X-Bow GT was given a lot of new go-faster bits and bobs, including a modified turbocharger for the 2-liter Audi petrol-fed powerplant, better exhaust, an optimized high compression pump and such. The ginormous rear wing with adjustable flaps is not that impressive when compared to the output hike - 485 HP and 520 Nm (383 lb-ft).
Pretty impressive if you consider that the standard KTM X-Bow GT produces 285 HP and 420 Nm (309 lb-ft). The Wimmer X-Bow R, however, isn’t as powerful as the GT. It’s 30 HP down at 455 HP and loses 20 Nm (14 lb-ft) of torque as well, but hey, it’s lighter than the GT so what you lose in terms of oomph you win on the scale. Finally, the track-only Wimmer X-Bow RR is the least powerful of the tuner’s trio.
With “just” 370 horsepower, that represents only a 10 HP bump over the RR’s standard tune, but this Austrian piece of kit is far better handling-wise as opposed to its R and GT siblings. This is the type of car that will blow your mind if you have the balls to thrash l it on a demanding circuit such as Laguna Seca.
If we’re to pick our favorite KTM X-Bow RR stat, that would definitely be the lateral acceleration this thing is capable of - a mind-boggling 2 Gs on semi-slick rubber is no small feat all things considered.
