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.

2013 Dinan S3 BMW 550i

Steve Dinan has been enhancing BMW models since 1979. But don't throw his company into the ring with the dozen or so other tuners who tweak, tinker and piggyback upgrades on the famed German marque. Dinan is a tuner, but it's also an engineering firm that writes its own software, builds its own parts and then backs everything it does with a factory-grade warranty. That sort of fastidiousness comes at a price, but most of its customers - including the powerhouse of BMW Motorsport - rely on Dinan to help them come out on top.
In stock form, BMW's 550i is a formidable four-door with a twin-turbocharged 4.4-liter V8 rated at 400 horsepower and 450 pound-feet of torque. While those figures allow it to run with quick company (0-60 in 5.0 seconds, according to the automaker), Dinan puts the sedan's kettle on full boil with its S3 package. Starting with the engine, the performance engineering firm bolts on larger turbochargers, air-to-water intercoolers, a trick strut tower brace cold air intake, a quad-pipe free flow exhaust and its own engine management software. Pump in some premium fuel, and the result is 542 horsepower and 587 pound-feet of torque. Power is sent through the stock eight-speed automatic to a limited slip rear differential (Dinan will upgrade xDrive all-wheel drive models, too).
The Dinan S3 also features and extensive suspension upgrade that includes new front camber arms and low compliance rear control arms (engineered to reduce understeer and improve turn-in). The stock dampers are retained, but new bump stops are installed along with new springs. Overall, the car rides about a half-inch lower than stock to improve roll rate. To reduce unsprung weight, forged 20-inch HRE Performance wheels are fitted at all four corners (wearing Michelin Pilot Super Sport tires - 275/35ZR20 up front and 295/35ZR20 in the rear). Lastly, the company remaps the factory Electronic Damper Control (EDC) software with its own Dinan Shockware to work in conjunction with the new enhancements.

2015 BMW 2 Series Cabriolet flips its lid [w/video]

Early next year, BMW will offer droptop versions of its entry-level 2 Series. Available in both 228i and M235i guise, the 2 Series Cabriolet will no doubt take everything we already like (and don't like) about the Twoer and add that wind-in-your-hair experience. Of course, taking in all the extra sun comes at a price - $37,900 for the 228i and $47,700 for the M235i, not including $950 for destination. Those prices represent increases of $5,800 and $4,600, respectively.
Powertrain specs are identical to the coupes, with the 228i powered by a 2.0-liter turbocharged inline-four good for 240 horsepower and 255 pound-feet of torque. The more potent M235i gets BMW's turbocharged, 3.0-liter inline-six, with 320 hp and 330 lb-ft of push, and can hit 60 miles per hour in 4.8 seconds. That's with the eight-speed automatic transmission, which is available with either engine. And for those who prefer to row their own, BMW will thankfully offer a six-speed manual gearbox with both powerplants, as well.
Following the Paris Motor Show unveiling, the pair will be shown in the US at the Los Angeles Auto Show in November before hitting dealers a few months later. Have a look at the new droptop in our fresh batch of images live from the Porte de Versailles exhibition center, and read BMW's lengthy press blast, below, for all of the official information.
