This onboard footage we found on his GoPro tells the story. It's from a race at Chuckwalla Valley Raceway in desert of southern California (where the Motorcyclist staff occasionally tests sportbikes) in which our esteemed colleague set a new lap record for the 350 Supersport class aboard his tiny, trusty steed. A lap time of 1:58.66 is a pretty arbitrary number, but consider this: To cover Chuckwalla's 2.7 miles and 17 turns Ari averaged 81 mph, just 11 mph slower than a stock CBR300's outright top speed of 92 mph. And, of the less-than two minutes it took to do the lap, the bike was wide open for one minute eleven seconds, or 60 percent of the lap.
