The engine in this bike is a 1,200cc XB unit with 42mm Mikuni flat-slide carbs and a Dyna 2000i ignition that’s good for 100bhp. Further work has gone into the BKG triple clamp which carries adjustable clip-ons with a “dogbone” design that allows for variations in height. The oil tank is finned and mounted on the front of the engine for effective cooling.
“On the first chassis, the oil tank was too high to bring the heavy battery as low as possible. But, we found a Lithium Ion batter from BF which weighs less than 900 grams, so we could move it up and bring the oil tank lower.”
The self-supporting tail was made by PRT and doesn’t include any metal support structure at all. The ZTL brake is a combination of an EBR disc with an ISR caliper. Wheels are tubeless spoked items from Alpina Raggi and the big analog speedo and shift light were made by Motogadget. The forward controls look like superbike rearsets and were made by LSL.
“It feels like a moped when you grab the handlebars, it’s so light,” says Jens. “And what weight there is is very low.”
“You can bore the XB12 engine with the stock stroke to 1,430cc, but that 100bhp should do the trick,” says Jens. “We geared the bike with our own sprockets so that it maxes out at 112mph. The acceleration in comination with the traction of that long chassis should be very competitive. For the ‘Busas, you push the NOS button.”
A wet NOS system was designed by Wizards of NOS to delivery an extra 25bhp at the push of a button.
The frame has already passed Swedish road-worthiness regulations and Pegasus is evaluating whether or not to submit it for EU type approval. It can accomodate all XB and Sportster motors. As a neat feature, the frame doesn’t require the XB’s swingarm pivots, which often break off in a crash. That means you’ll be able to build a Cerberus from a crashed XB for under €10,000.
