German tuner Wimmer has prepared extensive upgrade packages for the KTM X-BOW GT, R and RR.

First up, the X-BOW GT has gone through a series of engine upgrades which include a modified turbocharger, optimized high compression pump, bespoke exhaust and other similar tweaks bumping output of the four-cylinder, 2.0-liter turbo from 285 HP (210 kW) and 420 Nm (310 lb-ft) to 485 HP (357 kW) and 520 Nm (383 lb-ft). It’s enough for a 0-60 mph (0-96 km/h) run in less than four seconds and a 160 mph (257.5 km/h) top speed. It costs €130,000 and also includes a carbon rear wing with adjustable flaps along with some modifications to the chassis.

Up next is the X-BOW R which gets a power boost from 300 HP (220 kW) and 400 Nm (295 lb-ft) to 455 HP (335 kW) and 500 Nm (369 lb-ft). The €120,000 vehicle can do 154 mph (248 km/h) and is optionally available with a reinforced gearbox with sports clutch, uprated differential and chassis tweaks.

Last but not least, the track-only X-BOW RR also gets an output lift from 360 HP (265 kW) to 370 HP (272 kW) and a series of optimizations which have jacked up the price of the vehicle to €110,000.
