“Hercules II” Rocket Racer from Kraftstoffschmiede x Man & the Machines…  

The BMW R1250RS is without doubt one of the world’s finest sport-touring machines, constructed round a 1254cc shift-cam flat-twin that makes 134 bhp and 105 lb-ft of torque — extra stump-pulling kilos of grunt than a KTM 1290 Tremendous Duke and even the supercharged Ninja H2 SX.

“It devours miles, whether or not you’re within the temper to go far or go quick… The R1250RS is a very supreme sports-tourer.” –MCN

In inventory kind, the R1250RS is perhaps a long-range cruise missile, however Phil Ludwig of Germany’s Rennstall Moto and Kraftstoffschmiede (“Gas Forge”) had the concept to remodel the large German sports-tourer into an 1/8-mile rocket ship.

Phil’s earlier drag bike, a BMW R850R known as “Hercules,” was constructed to compete in Sultans of Dash — the European 1/8-mile dash sequence that spawned a mess of high-powered twin-cylinder rocket ships from workshops throughout Europe. The unique Hercules was good for 100 rwhp…earlier than Phil hit the 40-shot of nitrous tucked in a bottle beneath the saddle.

Phil was profitable with Hercules, incomes a Prime 10 end within the Sultans sequence, however he was reaching the boundaries of the older air-cooled platform. He appeared to the R1250RS for higher potential, inking a take care of BMW Motorrad for manufacturing unit backing.

“Very quickly a model new R1250RS with a full Possibility 719 package deal rolled onto the ramp at Kraftstoffschmiede. It was rapidly stripped all the way down to a naked rolling chassis and engine with the intention to lay out a plan for the construct.” -Kris Szews, Man & the Machines

Phil labored carefully together with his buddy and Rennstall cofounder Kris Szews of Man & the Machines to design, construct, and tune probably the most beautiful, most profitable dash bikes to come back out of your complete sequence: “Achilles.” The bike was designed to have the identical weight distribution and ergonomics as Hercules, however almost the whole lot else on the construct was {custom}.

The unique tail part was aluminum, housing the nitrous oxide bottle and engine administration, whereas Wilbers Suspension custom-made the fully-adjustable entrance and rear suspension. A set of {custom} CNC yokes have been produced to carry the forks, full with 50mm of additional offset for ideally suited weight distribution. In the meantime, the maestros at Hattech welded up a {custom} chrome steel exhaust system.

Achilles rolled on a set of custom-laced wheels courtesy of Kineo, and the fairing and monocoque with the BMW M-inspired design (pictured beneath) was printed by FKM Laser Sintering. Then there was the tuning:

EU5 emission laws…meant numerous sleepless nights for Phil, optimizing the engine setup on many dyno runs to carry out like an actual drag bike ought to. Additional, a better gear ratio taken from an R1250GS helps with the torque figures.” -Kris Szews, Man & the Machines

All these late nights proved worthwhile, as Achilles reigned supreme within the Manufacturing unit Class in the course of the 2019 Sultans of Dash sequence. However Phil and Kris have been simply getting began.

“In 2020 there have been a number of concepts how Achilles might seem like as a unadorned bike. So the concept was born of a homage to Hercules I. Right here it’s: Hercules II.”

Kris labored with Muniq Design to create a 3D mannequin primarily based on Achilles information and his personal sketches, and a brand new light-weight carbon monocoque was formed up. In the meantime, Ilmberger produced the opposite carbon components, such because the fan shrouds and stomach pan.

 

For 2023, the duo determined to redo the colorway, and Kris got here up with the BMW M-inspired livery the bike now bears.

From a efficiency angle, the purpose for Hercules II was 200Nm of torque (148 lb-ft) — a quantity that might require extra superior tuning.

Hattech got here by way of with one more trick exhaust — this time, the pipes snake by way of the swingarm. In the meantime, many extra hours have been spent on the dyno, tuning the bike for max torque within the 1/8 mile.

The result’s 160+ hp and 200+ Nm of torque with simply 80% of the nitrous shot — mission completed!
