Harley-Davidson's New 121ci CVO Engine Has VVT

A couple of days ago, we were tipped off by Harley-Davidson blogger Dr. Dan Morel about photos of an alleged new CVO Road Glide and CVO Street Glide taken from the factory floor. Morel has since sent us another photo, offering a clear look at the CVO Road Glide’s right side, including evidence that the new 121ci engine uses variable valve timing.

All-New, All-Singing and Dancing Groundbreaking Ducati V4 Granturismo 1158

All our conjecture was resolved early this morning when Ducati CEO Domenicali unveiled the new V-Four engine that will power the next generation Ducati Multistrada. The biggest surprise is that the new “Granturismo” 1158 engine will not use desmodromic valve actuation, but regular springs. That doesn’t seem like a bad thing in this application, as it gives the engine “record-breaking maintenance intervals”– 60,000 km or just over 37,000 miles. (It’s probably an excellent thing, in fact, since the mystery and expense of having to have one’s desmodromic valves adjusted has always loomed large for the non-wealthy when contemplating Ducati ownership.)

BMW Releases Details on "Big Boxer" R18 Engine

We were expecting BMW to debut its new “Big Boxer” cruisers at EICMA but were left disappointed with yet another concept model. We don’t have anything against concepts, really, but the R18/2 shown at EICMA was already the fourth to incorporate the new engine, and despite the spy photos that have popped up, it seems like BMW’s new cruisers just aren’t quite ready for full production yet.

Patent Filing Reveals New Harley-Davidson Pushrod Engine Design

It’s been a pretty busy week for Harley-Davidson, announcing its 2020 model lineup and holding its annual dealer meeting in Milwaukee. Judging from our readers’ comments, the news hasn’t been too impressive, with the highlights including the return of the Low Rider S, a new $48k CVO Tri Glide and the disappearance of a few notable models. For most of Harley’s returning lineup, the only updates are new colors and, for touring models, a new, optional suite of electronic rider aides. Those hoping for news of the Pan America or Streetfighter will be disappointed to hear Harley’s new liquid-cooled DOHC platform is still not ready for production.

Why Did BMW Build an 1800cc Boxer Engine?

Earlier this month, BMW and Japanese builder Custom Works Zon presented a rather industrial-looking retro-styled roadster at the 27th annual Mooneyes Show in Yokohama, Japan. The bike itself, christened the “Departed” by builders Yuichi Yoshizawa and Yoshikazu Ueda, was an interesting combination of vintage styling and modern production, making use of a lot of milled aluminum, steel piping and sheet metal and drawing inspiration from the bikes ridden by racer and landspeed record holder Ernst Henne in the ’20s and ’30s.

Honda CBR600-Powered Bumper Car!

This just in from the So Stupid We Wish We Had The Skills To Do It Department: Why not wedge a CBR600’s engine in a 1960’s bumper car chassis and go gunning for the World’s Fastest Bumper Car record?
