Cafe racer motorbikes storm Japan

Japan may be best known, at least among motorcycle enthusiasts, for its sport bikes. But as we found at the Tokyo Motor Show this year, Japanese motorcycle manufacturers are capable of producing all kinds of motorbikes. And to our delight, that includes cafe racers.
Along with the myriad electric bikes, dirt bikes, crotch rockets and scooters, the halls of Tokyo's Big Site convention center this year were full of the retro-infused rides we love. Chief among them was the Bolt (shown above) which Yamaha exhibited alongside their various electric two-wheelers, sporting a delicious metallic blue paintjob, inverted handlebars and hanging mirrors, machined metal bits, blacked-out trim and saddle brown leatherwork.
Honda was also on hand with a new EX version of its '70s-style CB1100 retro roadster in sinister and low-key matte black. And this was our first chance to check out BMW Motorrad's new birthday present to its 90-year-old self, the R NineT, a model recently unveiled at the EICMA motorcycle show in Milan. But one of the most amusing retro rides we came across was the Honda Monkey Limited, a mini bike that makes the new 125cc Grom (which was displayed alongside it) look positively gigantic.

BMW tests M Lap Timer App with M4 Coupe at Brands Hatch

The 2015 BMW M4 looks to include all the necessary ingredients to offer dynamite driving experience. It's an M car after all. But in today's constantly connected world, the experience of hurtling a car around a track isn't always enough.
We want data, and while there are some solid telemetry apps available for smartphones (notably Harry's GPS LapTimer), manufacturers have been a bit slower to develop their own dedicated mobile telemetry trackers for their performance cars. With the new M4, though, BMW is taking the plunge, allowing drivers to track their lap progress through a new app, creatively called the M Lap Timer.
To show off the program, BMW has recruited touring car racer Andy Priaulx to perform a fast lap in an M4 at the UK's Brands Hatch circuit. The accompanying video doesn't do much to show off the app in action. Rather, it give us a stylized look at the metrics as Priaulx hustles BMW's hottest 4 Series coupe around the circuit.

BMW looking to fix i3 acceleration problem uncovered by Consumer Reports

The BMW i3 has been hailed in some quarters as the future of electric mobility, what with its innovative carbon-fiber-reinforced plastic body and commitment to sustainable materials wherever possible. The modernist little hatch is even available with a 650cc two-cylinder gas engine with 34 horsepower to act as a range-extender for those who want it. However, that optional engine might have a drawback - at least for the moment.
Consumer Reports brought the problem to light when one of its drivers was behind the wheel of an i3 using the range-extender. When the driver attempted to pass another vehicle on a rolling, two-lane road, the BMW suddenly had no power to accelerate - a scary situation. CR started examining the car and found something pretty shocking: After driving at a constant speed for a while without any regenerative braking in range-extended mode, acceleration to 60 miles per hour plummeted from about 9 seconds normally to a staggering 27 to 40 seconds in their testing.
A BMW spokesperson told CR that it knows about the problem and has a fix coming next spring that also works on current models. The upgrade includes a state of charge indicator, a warning about loss of power and uses the car's navigation to boost the battery before driving on rolling terrain. It is not clear if the severe power deficiency will also eventually result in a recall.
