KR800 – Kawasaki Rotax 2 Stroke Street Bike

By Paul Crowe

KR800 - Kawasaki Rotax 800cc 2 stroke

What was I just saying the other day about not seeing very many mix and match frames and engines in custom bikes? Bill Shank thought we might like to see what he put together in his garage, his KR800, a Kawasaki ZZR1200 mated to a Rotax 800cc 2 stroke engine from a 2003 Ski-Doo. He isn't the first to mount a snowmobile engine in a motorcycle, but it's an interesting combo that, … [Read more...]

Royal Enfield Ace Fireball Cafe

By Paul Crowe

Ace Fireball 535 cafe racer

When you come up with an engine modification for the Royal Enfield called the Ace Fireball 535, it sort of defeats the purpose to slip it into a stock bike, except for the much greater performance, a lot of folks might miss it altogether. Chumma, one of the partners in the Fireball project, just finished his new Royal Enfield cafe. (correction: Chumma did the work on this … [Read more...]

NorKaw – Kawasaki Z1 Power Motivates a Norton Featherbed Frame by Mick King

By Paul Crowe

NorKaw - Norton Atlas frame with Kawasaki Z1 engine by Mick King

With today's specialized frames, wrapped around the specific engine they were designed for with no room to spare, we seldom see builders mixing and matching in a way that was common in years past. There are exceptions, like Norm Wilding's Kawabusa, for instance, a ZRX with Hayabusa power, but most of the customs work with the engine they came with. Mick King, whose NSU … [Read more...]

Motus MST Motorcycle on the Dyno and in the Cold

By Paul Crowe

Motus winter test ride in January in Michigan

We haven't been hearing much from Motus, but as Brian Case told me, "we've been underground for a while, but that's what Winter is for, to stay in the shed and build s#&t so you can get it done by Spring." And then he gets to ride the MST V4 test bike in January, not in Alabama, but in Michigan. Cold? Oh yeah, but that's what it takes. Link: Motus Now check out the video … [Read more...]

Hattar Motorsports Triumph Street Tracker

By Paul Crowe

Hattar Motorsports Triumph street-tracker

Hattar Motorsports in San Rafael, CA built a Triumph street tracker from a Scrambler. Lots of hand formed bodywork, custom frame, custom pipes and the engine was worked over, ... a lot. Starting at 450 pounds and 39 rear wheel horsepower they finished with 320 pounds and 100 rear wheel horsepower. Gorgeous bike but not cheap. After all of the discussion on the Kawasaki … [Read more...]

Norton NSU Special – A Sleeker Mini Mammut

By Paul Crowe

Norton NSU special by Mick King

Many of you remember the Munch Mammut, we've written about them several times on The Kneeslider, they were a fascinating motorcycle from the 1960s powered by an NSU auto engine. Very impressive engineering at the time but they looked a little ponderous, after all, that 4 cylinder engine wasn't designed to fit into a motorcycle, what would you expect? A few days ago, Mick … [Read more...]
