Major Brembo brake recall hits Ducati and Aprilia

avatar

Published

on

Brembo has issued a large scale recall of its PR16 radial master cylinder.

This master cylinder is often seen paired with the company’s popular M50 calipers and has come as factory standard on many motorcycles.

The recall is due to the manufacturing of the polymer piston (polyphenylene sulfide), which due to the injection process, creates a porous material that can crack under certain circumstances like track use, frequent ABS intervention or even a tip over. A failure of the master cylinder could result in a loss of braking force or a complete brake failure which could lead to a crash. The remedy for the problem is a replacement piston made out of aluminum instead of a polymer one.

At the time of this writing, the recall is isolated to the US and affects two models of Aprilia and six Ducati models:

2016-2017 Aprilia RSV4
2017 Aprilia Tuono
2015-2018 Ducati 1299
2015-2018 Ducati Monster 1200
2015-2018 Ducati Multistrada
2015-2018 Ducati Panigale R
2017-2018 Ducati Scrambler
2015-2018 Ducati xDiavel S

However this recall may effect other brands like KTM or Triumph, down the road. We will keep you abreast of any updates The recalls will be handled by the respective motorcycle manufacturers.

Please check with your dealer to see if your bike affected.

Aprilia will notify owners, and dealers will replace the front brake master cylinder piston, free of charge. The recall is expected to begin January 15, 2018.

Ducati will notify owners, and dealers will replace the front brake master cylinder piston, free of charge. The recall is expected to begin February 15, 2018

Whilst this recall and replacement of master cylinder pistons is currently US only, it’s believed that once begun, the same solution and process will start to roll out within the much larger and more complicated European region.

Custom of the Week: BMW R100RS by Bolt Motor Company

Published

MOST CUSTOM BUILDERS are juggling careers, building bikes as a side gig. Adrián Campos falls into that category: he’s the sporting director for Campos Racing, the team founded by his father Adrián Campos Sr, the former Minardi F1 driver.

Adrián Jr. is surrounded by high-tech missiles capable of 208 mph (335 kph), but he’s also nuts about motorcycles. So he started customizing classic bikes, as an antídoto to the ultra-modern race machinery that absorbs his working day.

His first build garnered enough interest to turn his side gig into a fully-fledged second business. Bolt Motor Company is now on its seventeenth build, and employs seven team members.

Bolt shares a workshop in Valencia with Campos Racing. But while the race team preps cars for the Formula 2, Formula 3 and GP3 race series, Adrián is swinging spanners on bikes like this stunning 1982 BMW R100RS.

We’ll admit it’s not the wildest custom boxer we’ve seen. But even though the style is well established, the perfect proportions and level of finish are something else. And the client wasn’t even looking for anything fancy; “He wanted a comfortable cafe racer for two people,” says Adrián, “so that’s what we did.”

The donor arrived in a pretty good condition, but it left in an even better state. There’s fresh paint and powder everywhere, from the motor right through to the forks, frame and tank.

Bolt tweaked the airhead’s stance by lowering the front forks internally just over two inches, then installing a pair of Hagon shocks at the rear. The fuel tank is stock, but the subframe and seat are custom made. The subframe’s a bolt-on affair, and the main frame’s been detabbed and cleaned up.

The taillight’s a particularly nice touch. Bolt built it into the seat rather than the rear loop, along with integrated rear turn signals. The whole setup’s barely visible—until it lights up.

They’ve also added some room for the customer to ‘customize’ his BMW at home. There’s a second tank and seat in a different paint scheme, which can be swapped out via four fasteners for the seat, and one for the tank. The second seat has it’s own plug-and-play taillight too.

Bolt have kept things practical too. The BMW’s airbox is still in play, and it’s also equipped with a BMW oil cooler and crash bars. Plus there’s a discreet inner fender at the rear. The exhaust headers have been shortened and run into a pair of generic cone mufflers, with the side stand relocated to work around them.

The cockpit’s sporting new handlebars, grips, bar-end mirrors and Motogadget bar-end turn signals. There’s a new master brake cylinder too, with some really neat plumbing. Up front is an LED headlight, tucked into a custom-made bucket.

Bolt rewired the bike from top to bottom and tucked away as much as they could. A set of Motone switches have their wires running inside the bars, while a Motogadget speedo has its cable routed through the BMW’s hollow steering stem nut.

This sort of consideration is rife, with every last nook and cranny cleaned up. We’ve spotted stainless steel fasteners throughout the build, nifty choke pulls on the carbs and a OEM-looking Bolt Motor Co. plaque on the side of the motor.

The classic white BMW motorsports livery is on point too. And Bolt have shunned the ubiquitous Firestone Deluxe Champion tires, going for the saw tooth tread of Shinko Classics instead.

We doubt that Bolt #17 could lap a track anywhere near as fast as a Campos race car.

But it’s just the sort of simple, classic ride we’d pick for getting to the track in the first place—via some leisurely Spanish back roads.

Video: Watch Sarah Lezito show you how to drift a motorcycle

Published

on

Yes, drifting on two wheels is possible. Especially if you’re an insanely talented stunt rider from France.

There are a few stunt riders worth following across social media and YouTube but few get the numbers of French stunter Sarah Lezito.

Shot in a cold, wet and snowy location, it’s hardly the easiest of environments for riding a motorcycle – although possibly better for skids! – but the control from Lezito, and her instruction, is captivating.

Why learn how to drift? Well, Lezito says that it might help in learning how to save from slipping, keeping the balance on your bike or just improving your stunting skills.

And her top tips?

  • First find a small bike – a 50cc or 125cc machine that’s easy to handle.
  • Find a slippery spot, like a wet floor after some light rain.
  • Put hard tyres on the rear and more air in the front tyre.
  • Protect everything… On you and your bike.
  • Prepare to crash. A lot.

We’re hoping she’ll be adding to her channel over the coming months and that this is the start of a series of ‘How To…’ videos from the young stunt rider.
