The Ronax: A 500cc GP Bike To Call Your Own

It is not often that we have cause to write about road-going motorcycles, but this is something a little bit special. The German engineering company Ronax have released a 500cc two-stroke V4 track missile, a cross between a Honda NSR500 and Yamaha YZR500. The bike is an 80° V4 two-stroke featuring two counter-rotating cranks, a design similar to Yamaha's 500cc GP machine, the two counter-rotating crankshafts balancing each other's inertial torque out. The bike features electronic fuel injection, and comes in at a paltry 145kg dry weight. The weight is kept low due to extensive use of aluminium and carbon fiber parts, the bodywork, tank, rear seat unit and airbox all being produced from CF. Quoted power is 160bhp, a fair few short of the 200 generally ascribed to the last of the 500cc Grand Prix racers.

America's Next World Champion? PJ Jacobsen On What It Takes To Race In World Supersport

With Ben Spies already retired, Colin Edwards about to retire at the end of the 2014 season, Nicky Hayden struggling with a wrist injury and Josh Herrin having a very tough rookie year in Moto2, there is growing concern among US fans about the future of American racing. What is to become of the nation that once dominated world championship racing, with existing stars in decline and no fresh blood ready to replace them?

Perhaps the brightest point in the firmament for American racing is PJ Jacobsen, currently racing in the World Supersport championship for the Kawasaki Intermoto Ponyexpress team. The native of Montgomery, New York has been quietly building a reputation as a fast and promising young racer, stringing together a series of top ten results in the competitive WSS series in his debut year, and coming very close to scoring his first podium. Jacobsen's World Supersport debut comes after an impressive first year racing in the British BSB championship with Tyco Suzuki, which earned him a move to the world stage.

We caught up with Jacobsen a few weeks ago at Assen, ahead of the third round of the World Supersport championship. There, we spoke to him about the state of American racing, the difficulties faced by American riders trying to break into a world championship, and the path he took to the world stage. Jacobsen covers BSB, living in Northern Ireland and how his background in dirt track helped in road racing. PJ tells us about how BSB is a viable route into a world championship, and just what it takes to make the move. It was a fascinating perspective from an extremely talented young racer. 

MotoMatters.com: First, a little background on you. You started your career racing with Barry Gilsenan in the AMA with Celtic Racing?

PJ Jacobsen: I've been racing for [Barry Gilsenan] since I was twelve, he was the first person that got me on a bike.

MM: He got you onto a bike, he got you racing, what was your path to World Supersport?

PJ: I was racing 125s in the USGPRU series in the US. He got me involved in that, and I won a title with him in the States. Then I came to Europe to race in the Spanish championship, and was in the MotoGP Academy. Then I went back to the US and rode for them in the AMA on a Suzuki 600. I rode for them for three years in the States. I rode in the Daytona Sportbike class, that's when everything was kinda turning around there.

2014 Sepang World Superbike Race Two Results: Race Restarted After Burning Bike Brought Out Red Flag

World Superbike race two started at 16:30 local time, with the schedule being shifted for the main markets to be able to see the racing.

The race started with Toni Elias taking the lead into turn one from an excellent start, with Sylvain Guintoli pushing past a few turns later when Elias wobbled out of a corner. Tom Sykes, with his wrist injured in the first race, was third until Marco Melandri passed him, setting up an Aprilia 1-2-3 ahead of a Kawasaki 1-2 tailed off by Baz.

On the fourth lap, Guintoli started eking out a lead from Elias but the red flags were brought out after Claudio Corti's MV Agusta leaked fluids onto the track and caught fire, much to Corti's surprise.

2014 Sepang World Superbike Saturday Roundup: Humidity But No Rain Yet

It rains almost every day in Sepang, and yet it has been dry for the last two days. Rain is predicted for Sunday, but that doesn't mean it's a certainty. Heat and humidity, however, are. New riders need to be reminded to take their helmets off when they get back to their pit boxes, and plenty of fluids need to be ingested.

The Hermann Tilke designed Formula 1 circuit suits motorbikes more than other car tracks, but the bumps, caused by braking cars pushing the tarmac into corners like a carpet against a wall, can still catch riders out, especially at the end of the faster stretches where you have to tip your bike in over corrugated road.
