Consumer Reports' first motorcycle reliability report finds Japanese brands ahead

Consumer Reports has released its first ever study of motorcycle reliability, and students of its ratings on cars might notice a suspicious similarity - Japanese brands require fewer repairs than the leading American or German brands.
The study analyzed the reliability of 4,680 bikes owned by CR subscribers and found that Yamaha had the best ratings, with just one in ten bikes built between 2009 and 2012 requiring a repair over a four-year period. The makers of the R1 and R6 sport bikes were closely followed by Kawasaki and Honda, while one out of every four of the rumbling bikes from Harley-Davidson experienced an issue. BMW had the worst rating of the brands represented, with one in three bikes having problems.
According to CR, neither Suzuki nor Triumph owners provided enough information for a reliable rating. Based on the responses received, though, Suzuki would have finished with the other Japanese brands and Triumph, being English, would have been one of the less reliable makes.

Is the skill of rev matching being lost to computers?

If the ability to drive a vehicle equipped with a manual gearbox is becoming a lost art, then the skill of being able to match revs on downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. The usefulness of rev matching in street driving is limited most of the time – aside from sounding cool and impressing your friends. But out on a race track or the occasional fast, windy road, its benefits are abundantly clear. While in motion, the engine speed and wheel speed of a vehicle with a manual transmission are kept in sync when the clutch is engaged (i.e. when the clutch pedal is not being pressed down). However, when changing gear, that mechanical link is severed briefly, and the synchronization between the motor and wheels is broken. When upshifting during acceleration, this isn't much of an issue, as there's typically not a huge disparity between engine speed and wheel speed as a car accelerates. Rev-matching downshifts is the stuff they would teach at the automotive equivalent of the Shaolin Temple. But when slowing down and downshifting – as you might do when approaching a corner at a high rate of speed – that gap of time caused by the disengagement of the clutch from the engine causes the revs to drop. Without bringing up the revs somehow to help the engine speed match the wheel speed in the gear you're about to use, you'll typically get a sudden jolt when re-engaging the clutch as physics brings everything back into sync. That jolt can be a big problem when you're moving along swiftly, causing instability or even a loss of traction, particularly in rear-wheel-drive cars. So the point of rev matching is to blip the throttle simultaneously as you downshift gears in order to bring the engine speed to a closer match with the wheel speed before you re-engage the clutch in that lower gear, in turn providing a much smoother downshift. When braking is thrown in, you get heel-toe downshifting, which involves some dexterity to use all three pedals at the same time with just two feet – clutch in, slow the car while revving, clutch out. However, even if you're aware of heel-toe technique and the basic elements of how to perform a rev match, perfecting it to the point of making it useful can be difficult.

BMW M2 reportedly green-lit

A BMW M2 is on the way, according to a sub-forum in the Bimmerpost empire. Of course, we're actively enjoying a few grains of salt, just to be safe, as the post doesn't mention explicit sources, saying only that "multiple inside sources (who have been accurate in the past)," have confirmed the car.
Provided the forum is correct, though, there's some juicy information here. Production is allegedly slated for late fall 2015, with deliveries likely starting in early 2016. The new sports coupe should arrive with 365 to 375 horsepower, courtesy of an upgraded version of BMW's N55 turbocharged, 3.0-liter inline-six.
The report claims BMW also considered a modified version of the 2.0-liter, turbocharged four-cylinder found in the Mini Cooper S. That engine, known internally as the B48, would have been called the S48 for M2 duty, a significance that we're sure BMW purists would appreciate (the only BMW engine to wear an S designation was the four-cylinder from the legendary E30 M3).
