The Best Custom Motorcycles In The World, July 17th 2014

Welcome to The Week In Bikes, your weekly CliffsNotes version of the best new custom bikes in the world.

Motorscompany's Yamaha RD350
Motorscompany is a small Brazilian shop that's not afraid of taking on any project. This 1987 Yamaha entered their shop fit for a junkyard and not much else, but a few zillion parts later, it's a proper street-fighter with a custom rear subframe supporting an array of parts from Buells, Suzukis, Triumphs, and of course Yamahas. H/T: Pipeburn

Ellaspede's Honda GB250
The Australian bike-masters at Ellaspede just proved the old adage that good, classic bikes don't need much to stay fresh. The engine was rebuilt with little more than some custom exhaust work added. Meanwhile, cosmetically, little was done besides some clean up work and swapping the ancillaries with almost entirely off-the-shelf parts that resulted in an understated custom that both rides like new and should last for a few decades.

HGarage's Yamaha XT500
This bike was a slow evolution—it took a few months of driving before the decision to start modifying it was even made. The original plan called for a lower, more sleek appearance, but it required too many sacrifices to ride quality. Pretty much everything on the bike is either a heavily modified junkyard piece, or completely fabricated out of scrap. It's good to have friends in the blacksmith business, apparently. H/T: Pipeburn

The Radical Ducati BMW Interceptor
Sure, a shop with a name like Radical Ducati building something that's anything other than a Ducati is a little confusing, but this BMW boxer's good enough to forgive the name flub. Originally inspired by a police motorcycle from a comic book, the Interceptor actually does have plenty of Ducati parts, mostly around the wheels and brakes, to go with a seriously souped up BMW R100 motor.

Ad Hoc's "Haptica" Ducati
Starting with a 2004 Ducati Multistrada 1000 DS, the guys over at Ad Hoc stripped away as much as they could possibly get away with, then tucked all the unsightly electrical bits inside a custom box within the frame. Out back, you can change just four bolts and switch this from a one to two seat bike.
