KTM and Husqvarna recently announced that they will be producing two fuel-injected two-stroke models for 2018, as part of their respective enduro lineups. (The Husqvarnas will be essentially rebadged KTMs, as are most of the company's models.) While most manufacturers, including KTM and Husqvarna, offer a range of two-stroke dirt…

One rider aid that is available on an increasing number of new motorcycles is cornering ABS, sometimes incorporated into a stability control package. In its basic form, a cornering ABS function takes into account the motorcycle's lean angle to adjust brake pressure, increasing the ABS effectiveness beyond a simple straight-line…
While variable valve timing has been a hot topic over the last few weeks with the introduction of the updated GSX-R1000 featuring Suzuki's innovative mechanical VVT system, many companies are working toward the next step in this area: eliminating camshafts completely and controlling the valves directly using electromagnetic actuators. There…
At the final rounds of this year's Mopar Canadian Superbike Championship series, held at Canadian Tire Motorsport Park, Dunlop offered qualifying tires to the top 10 riders for a separate, 15-minute final qualifying session. This was new for many of the competitors, as qualifying tires have not been used in…

We see all the time now road racers "backing it in" to corners, sometimes with the rear end of the motorcycle out of line with the front just as much as dirt track or supermoto racers. Using engine braking or the rear brake, these riders are skidding the tire just…
In previous blogs, and in the print version of the magazine, I have discussed anti-squat and how it relates to chassis setup. Anti-squat is a very important tool in making a motorcycle lap quickly at the racetrack, especially a powerful superbike, but at the same time it's one of the…

Over the past several seasons of MotoGP, Ducati has occasionally experimented with wings on the side of the Desmosedici to influence its aerodynamic characteristics. Yamaha also used wings in the latter part of last season on the M1, and wings have sporadically appeared on other bikes in the past. Until…
At the Tokyo Motor Show last year, Yamaha introduced its Motobot, a humanoid robot that rides a YZF-R1. Video was released showing the Motobot riding in an open area, mostly going in a straight line, but the intention is for Motobot to ride the bike on track sometime next year…
We know that riding smoothly is one aspect of quicker lap times at the track and being safe on the street: Gentle, precise throttle inputs, fluid body movements and steady lean angles mid-turn are just some of the characteristics of what you'd consider a smooth rider. Jorge Lorenzo is a…

Watch any road race practice session and you will see riders trying different lines almost every lap, as they search for the quickest way around the track. By race time the experimentation is done and the top riders rarely stray more than a few inches from their chosen lines, but…
With just a handful of rounds remaining in this year's MotoGP World Championship, it's almost certain that the championship will go to either Valentino Rossi or Jorge Lorenzo. The two Movistar Yamaha riders are atop the standings, both with more than a race worth of points in hand over Marc…
Thanks to the popularity of NASCAR, most people are familiar with drafting and how it works. Obviously it plays a big part in stock car racing, but it's also important in motorcycle racing - especially at tracks with long, fast straights.

The first round of the 2015 Mopar CSBK series, held at Calabogie Motorsports Park, is in the books. This year I am again working with Jodi Christie and the Honda Canada/Accelerated Technologies team, looking after data and electronics on Jodi's CBR600RR and CBR1000RR SP.
After four rounds of the 2015 MotoGP season, Valentino Rossi sits atop the standings, with two victories and four podium finishes to his credit. While the Movistar Yamaha rider has definitely taken advantage of his competitors' various misfortunes in the opening rounds, he has just as definitely shown he is…

In any racing effort, from club-level novice to national pro and the world stage, testing plays a vital role. For inexperienced riders, it's more about learning the basic skills of road racing, trying new techniques and simply learning to ride better. At that beginning level, any riding at all can…
In the works for more than a year now, Ducati finally introduced its Desmosedici GP15 MotoGP bike at the Sepang test last month. The results were quite promising: Even though the bike had barely turned a wheel before the test, Andrea Iannone posted the fourth-quickest time of the three days…
Not long after Jodi Christie clinched the Mopar Canadian Superbike Championship at Canadian Tire Motorsport Park in August last year, John Sharrard - who runs the Accelerated Technologies/Honda Canada team and is Jodi's crew chief - and I were busy plotting Jodi's title defence for this year. History shows that…
