We have drooled over Walt Siegl’s work before. First, it was the forged carbon Bol d’Or made in collaboration with David Yurman, which was followed by the Leggero model.

Our love affair ramped up with Walt’s Dakar-inspired Hypermotard, which was then followed by an even more adventure-ready machine built off the same platform, aptly named L’Avventura.

These bikes have helped to solidify Walt Siegl as one of the great motorcycle builders in the United States, and today’s addition only further bolsters that notion. As such, we bring you the simply named SBK models from Walt Siegl Motorcycles.

Bimota is known for making drool-worthy motorcycles, and at EICMA the boutique Italian brand debuted two fine motorcycles. But, we think the real show-stopper for Bimota was its add-on supercharger system for its Ducati-powered motorcycles.

Good for 15% to 20% more power (probably more, if you like to tinker), the Bimota supercharger kit uses a Sprintex dual-screw supercharger, which has been tastefully made to match the belt covers on the Ducati Testastretta engine.

As you can see from the photos below, the supercharger looks pretty damn good, especially when paired with the “Bimota Experience” package, which adds a carbon fiber frame and swingarm to the chassis.

The Bimota Impeto is the first model to officially have the supercharger as an option, but the Italians say it can be made to work with any of its water-cooled Ducati-powered models.

Bimota continues to impress, ahead of the company’s new-model debuts at the 2015 EICMA show. Not only will Bimota have two new models to show us, the Bimota Tesi 3D RaceCafe and Bimota Impeto, but the brand from Rimini says it is also getting into the forced induction game.

As such, Bimota has developed its own supercharger, which will be available on all of the company’s Ducati-powered engines that are liquid-cooled, which effectively means the DB8, DB9, & and DB11, as well as Bimota’s models that will debut in Milan, Italy this week.

That should be good news to those owners, as the Bimota supercharger is said to add roughly 15%-20% to the maximum torque figure, as well as smooth out both power and torque delivery.

It is only logical that if there’s a new water-cooled Triumph Bonneville T120 for the 2016 model year, then the 2016 Triumph Thruxton should get an update as well, right?

Accordingly for 2016, the Triumph Thruxton gets the same more powerful 1,200cc liquid-cooled parallel-twin engine that is debuting on the Bonneville T120.

Triumph is also adding the Thurxton R to the lineup, a more cafe racer inspired design that comes with a larger front fairing, Öhlins suspension, and Brembo brakes. An optional “Thruxton Inspirational Pack” is available as well, which adds a bevy of cosmetic changes, as well as a Vance & Hines exhaust system.

Like on the Bonneville, the chassis and other components have been improved upon as well, though you would have a hard time seeing those changes, as Triumph has been careful to retain that heritage look on the Thruxton.

We expect that retro-riders who are looking for a reliable café racer out of the box will need to look no further than the 2016 Triumph Thruxton. Expect to see the machine officially debut tomorrow, October 28th.

It’s been no big secret that Triumph is about to add liquid-cooling to the venerable Bonneville and its ilk. The cult classic hasn’t changed much in its long and storied past; and don’t worry, beyond the liquid-cooling, it hasn’t changed much for the 2016 model year either.

Thankfully, Triumph has kept the Bonneville aesthetic well inline with what discerning retro-riders and hipsters are looking for in their motorcycles, discretely hiding the machine’s blacked-out radiator.

While the 865cc Triumph Bonneville T100 will still come to the USA for the 2016 model year (free of the EU’s new stricter emission standards), the 2016 Triumph Bonneville T120 will travel worldwide, with its 1,200cc parallel-twin engine.

That headline is a bit of a misnomer, since the new liquid-cooled Triumph Bonneville has been “spied” for some time now in the media.

Triumph is at least capable of admitting that its hipster machine is getting an update now, releasing this teaser video that hints at “something big” coming our way – if liquid-cooling an engine is something big, then we couldn’t agree more.

As expected, BMW Motorrad has finally added its liquid-cooled boxer engine design to the R1200R roadster model, debuting the 2015 BMW R1200R at INTERMOT today.

Using the same 125hp engine that powers the BMW R1200GS and BMW R1200RT, the new BMW R1200R makes more power, more linearly, than its predecessor, though keeps the old R1200R’s basic roadster look and feel intact.

Once we saw the unveiling of the Ducati Monster 1200 at EICMA last year, we knew it was only a matter of time before Bologna wedged its new 821cc liquid-cooled motor into a mid-size Monster machine.

That feeling was fueled further by spy photos the 821cc Monster making their way onto the internet, and now we have confirmation of the mid-sized Monster, as Borgo Panigale has officially launched its Ducati Monster 821.

Borrowing the 821cc Testastretta 11° engine (112hp and 65.9 lbs•ft) found on the newly revised Ducati Hypermotard, and its cousin the Ducati Hyperstrada, the Monster 821 continues Ducati’s trend to repurpose powerplants for multiple product families.

The Ducati Monster 821 also continues Bologna’s new trend of building its lower-spec midrange motorcycles with double-sided swingarms, to help further stratify and differentiate its models.

At the German Auto Show, the Boys from Bologna debuted the Ducati 899 Panigale, a “super-mid” version of the Italian company’s superbike platform. A bit too big to be a supersport class machine, the 899 Panigale should however be fun on the track, in a vein that is similar to the Suzuki GSX-R750 and MV Agusta F3 800.

That premise will have to remain as conjecture for us though, as while Ducati’s chosen few are currently gathered in Bologna right now for the press launch of the 2013 Ducati 899 Panigale, Asphalt & Rubber was not among those who crossed the pond for the launch and test ride. Not to worry though, we should start hearing the initial impressions from journalists shortly.

Meanwhile, we can turn our attention to the machines that Ducati has yet to debut to the public, though will be shortly. A&R broke the news last week about the upcoming Ducati 1199 Panigale R Superleggera, and we have already seen spy photos of the Ducati Scrambler (said to be a 2015 model, if it gets the production nod), and a liquid-cooled Ducati Monster 1200.

Harley-Davidson has debuted its 2014 touring and trike motorcycles, which would normally be an event that we’d forgo even mentioning here at Asphalt & Rubber, after all “brand new” to Harley typically means new paint and chrome pieces to bikes that already exist in the line-up — that’s not entirely the case this year though.

Rolling out eight “new” motorcycles for enthusiasts, Harley-Davidson has listened to customer feedback and made changes to the following models in its line-up: Road King, Street Glide, Street Glide Special, Electra Glide Ultra Classic, Ultra Limited, Tri Glide Ultra, CVO Ultra Limited, and CVO Road King. Nothing crazy there, right?

However what was called “Project Rushmore” inside the motorcycle company, we now know refers to the company’s effort to bring more technology to its two-wheeled midlife crisis machines… the most drastic change being a liquid-cooled engine design. We’ve got your attention now, don’t we?

Debuting two liquid-cooling engine configurations, the Twin-Cooled High Output Twin Cam 103 motor will be used on the 2014 Harley-Davidson Ultra Limited and the Tri-Glide Ultra trike, while the Screamin’ Eagle Twin-Cooled Twin Cam 110 will be featured on the 2014 Harley-Davidson CVO Limited.

Building off of three decades of tradition and 170,000 units sold worldwide, the 2013 BMW R1200GS has some big shoes to fill. Officially debuting today at the INTERMOT show, the Bavarians have kept most of what makes a GS a “GS” intact, while of course adding a much speculated, hyped, and rumored water-cooled boxer-twin motor into the mix.

The big push with the new model is its ability to meet stricter noise and emission standards, hence the move to liquid-cooling. Though, BMW says it also aimed to improve the R1200GS’s on & off-road performance, increase the bike’s safety, and of course continue the GS heritage that has basically defined the segment.

Using “precision cooling” derived from Formula 1, the 2013 BMW R1200GS only uses liquid cooling on the parts of the motor that need the additional heat exchange, thus allowing the engine still to use a high-degree of air-cooling, which BMW says helps justify the continued use of the boxer-twin motor design. Other changes include a wet slipper clutch and left-hand side cardan shaft drive. As we reported earlier, power is 123hp and 92 lbs•ft of torque at 6,500 rpm, while the curb weight is 525 lbs (238 kg) without fuel.
