Three years ago, Ritmo Sereno of Tokyo produced a stunning orange BMW R80 track bike—the highly successful ‘Nakajima’ racer. Now a Ritmo customer has commissioned a road-going version—and this is it. It’s based on a 1991 R100 RS, but many of the other details are close to the track machine. The suspension is Öhlins front and back, the brake system is from Brembo and carburetion is Keihin FCR. Ritmo has paid a lot of attention to weight, so the 230kg-or-so of the stock machine has been reduced to a gossamer 175kg. (The battery holder, oil catch tank and the frame from the engine backwards are handmade in lightweight aluminium alloy.) Power is now around 80bhp at the back wheel, helped by a custom-made 2-into-1 exhaust system routed through a modified center stand. Ritmo has documented the entire build on its website—the link is here (via Google Translate). The level of craftsmanship is extraordinary, but if the authentic orange paint job is a little too garish for you, check out the original and (equally illustrious) Nakajima racer, a lovely blue R90/6. Is there a better custom BMW builder in the world today?

Jeremy Cupp of LC Fabrications has a truly original style when it comes to customization. However, he is known as custom bike builder who works with Harleys and Triumphs, but somehow a Yamaha made its way to his garage. The story begins with Bruce, a really nice guy who has it all: big black trucks, sweet little roadsters and all the fine women. Bruce, picked up a ’79 XS650 with only 11K on its 31 year old odometer but the bike sat for over a year in his garage. One day Bruce decided to donate this f-n Yamaha to the cause and this and where Cupp and the chicken shit (the f-n Yamaha) met.
Cupp had other things to take care at that time, but the bug was in his mind: the XS650 was only half finished and it was just sitting around, with some really cool ideas. He than decided to screw the Panster project and began his work on the Yamaha exploring the possibilities. The result? A beautiful and compact tracker-style custom with hard-tail back end and a cantilevered seat. The motor received some attention too, it was boosted with a 750 cylinder kit, 36mm Mikuni round slide carburetion and mild porting. Yes, Cupp can make chicken salad out of chicken shit.
