Tony Prust does not do issues in half measures. The person behind Analog Motorcycles took up monitor racing six years in the past, piloting a modified KTM EXC530 in supermoto occasions. A yr later, he was attempting to find glory within the Battle of the Twins 2 class aboard a purpose-built Ducati, ultimately claiming the nationwide title in his third season.
Within the years since, the sequence has grow to be extra aggressive—as has Tony. So he is parked that bike, changing it with this wild Ducati 750SS and Monster 796 hybrid, which he is dubbed System 840. As we have come to count on from Analog, each nut and bolt represents a thought of alternative, knowledgeable by years of expertise.
The challenge was conceived when Tony and his teammate, Del Thomas, have been spitballing methods to go sooner. Del owns and funds the Analog race bikes, and was prepared to drag the set off on a substitute.
“The Hyper8 [Analog’s outgoing race bike] did not have good aerodynamics, we misplaced all the weight we might, and it had some floor clearance points,” Tony tells us. “It was decided that we wanted to construct one thing from the bottom up.”
“We began the method on the finish of final yr, attempting to kind out what chassis we have been going to make use of. We thought of a number of the liquid-cooled four-valve Ducatis, however upon a lot investigation, it was determined that the SuperSport would in all probability be the perfect candidate. Then, in February, we crashed the Hyper8 on the final wet race of the weekend.”
“Though it fared effectively, it is unhappy to say, however the Hyper8 is now retired. We fast-tracked the System 840 challenge to get it prepared for this season.”
The Battle of the Twins 2 class is for air-cooled twin-cylinder bikes beneath 904 cc. Set on sticking with Ducati, Del sourced a 1999 Ducati 750SS that had already been prepped for monitor use. With a Ducati Monster 796 engine, an Öhlins rear shock, and light-weight magnesium wheels already put in, it was the proper start line.
“Past that, we re-did every little thing,” says Tony, bluntly. He is not kidding both—for starters, the engine was yanked out and shipped off to Al at Moto Corse Efficiency for a complete makeover. Whereas that was occurring, Analog began shaving weight off the 750SS chassis.
First, the hefty metal subframe was hacked off to make method for a hand-crafted bolt-on aluminum unit. An aluminum swingarm from Metmachex was put in decrease down, whereas adjustable billet yokes from IMA have been fitted up entrance, accommodating a set of Ducati 1098 forks. The forks have been handled to race cartridges by Race Tech, whereas the shock went to Öhlins for a rebuild.
Customized wheel spacers have been fabricated to match the entrance wheel to the brand new forks. For the brakes, Analog ordered a full setup from Beringer, ending it off with Spiegler traces. An Öhlins steering dampener and Vortex sprockets have been added too.
Shifting to the bodywork, Analog drew inspiration from the Ducati sportbikes of the 80s. “The membership that we race with is the American Historic Racing Bike Affiliation,” says Tony. “They seem to be a historic racing membership that has classic and fashionable bike lessons.”
“Technically, ours can be thought of a contemporary bike class, however we determined it might be type of cool to have a extra retro-looking bike. So we determined to make use of the 80s Ducati 750 F1 bodywork and retrofit it to the SuperSport setup. Thus the title, System 840.”
Interval-correct 750 F1 bodywork was matched to an ETI gas tank and carbon fiber fenders. Analog needed to bounce by a number of hoops to make every little thing match. The listing of one-off components contains the higher fairing bracket, further panels that create a cohesive vibe, and spacers to cease the fairing from interfering with the underslung exhaust.
The tailpiece was modified barely, too, earlier than being topped off with a customized seat pan. Angie Dixon dealt with the upholstery, Shinobi Paintworks painted the bike in Analog’s normal racing colours, and Enamel Model provided the graphics. Southern Powder Coating dealt with the body and subframe, ending each in a hue taken from the Ducati 916 Senna.
As soon as the Monster 796 engine was again from Moto Corse Efficiency, it had been rebuilt with an 840 cc package, outsized valves, upgraded cams, and ported heads. The consumption was modified with outsized throttle our bodies, Moto Corse consumption stacks, and Okay&N filters. Additionally on the listing have been a Yoyodyne slipper clutch, a Dynojet quick-shifter, and an H2O oil cooler.
Analog rewired the Ducati from high to backside, including a Microtec ECU and AIM dashboard with information logging capabilities. Analog sponsor Wirecare provided the braided wiring sleeves, warmth shielding, and oil traces and fittings.
The group additionally handled the bike to Vortex clip-ons, Woodcraft rear-sets, and R&G Safety body and axle sliders. Ending the Ducati off is a surprising chrome steel exhaust system, terminating in a pair of Cone Engineering mufflers. The asymmetrical design takes inspiration from MotoGP bikes, with one muffler exiting low on the right-hand facet and the opposite tucked beneath the tail.
“Your complete bundle ended up at 340 lbs with half a tank of gas, and our present tune places us at 89 hp on the wheel with room for enchancment,” says Tony. “Now, with the added aerodynamics, this must be fairly the monitor weapon in its class.”
“We took it for its first shakedown weekend in August at Blackhawk Farms Raceway and got here dwelling with two hard-fought first-place trophies out of the gate. An enormous shout-out to Del for trusting me with the challenge and permitting me to race his machines.”
Analog want to thank their title sponsor Wirecare, in addition to R&G Safety, Spectro Oils, Beringer Brakes, Okay&N Filters, and Enamel Model for his or her help.
