The Kawasaki Z1R TC is just one of the turbocharged machines produced by the major motorcycle manufacturers for a short period of time. In theory, a turbo comes as close to producing free horsepower as anything ever invented. It uses exhaust pressure to spin a small turbine that packs more fresh air and fuel into the cylinders. This creates a real-world, on-demand hyperdrive, which amounts to a very serious, very noticeable performance boost. But the heavy, ill-handling machines never really caught on with the public. This bike produced a claimed horses at 8, rpm. The engine is a 1,cc, air-cooled, turbocharged, double-overhead-cam inline four.

Norton Commando Production Racer. When some wealthy collector finally builds the ultimate motorcycle museum and designates one wing as the Hall of Influential Motorcycles, it’s not likely future visitors will see a Norton Commando Production Racer there. By most of the accepted methods of the definition, the bike simply wasn’t that important, especially outside Great Britain. It began life as a race-shop project, was launched as a marketing gimmick and, after a brief spurt of dominance and popularity on the British and European racetracks, went the way of other, suddenly uncompetitive racing machines.
Which is to say, into oblivion and numberless pieces. And yet there exists reason to think otherwise of the bike the British press instantly christened the “Yellow Submarine” on its debut at the Racing and Sporting Motorcycle show in London in a freezing January in This Production Racer a box-stock, genuine factory-built device, not some “prodified” aftermarket machine could well be considered the Ultimate British Vertical Twin. Assuredly, there are Triumph Bon-nevilles being sold as new even today.
But even the most wide-eyed Bonnie fan will have to admit that actual development of that machine stopped well before the workers’ co-op began building the bike in the mid-Seventies. Only Norton, of all the British bike manufacturers, attempted to come to grips with the inherent vibration of a big OHV vertical twin, and thus only Norton’s Isolastic-framed Commando, designed by Bob Trigg and launched in , can be said to have dragged the venerable old vertical twin into the postwar world.
Thus by the ineluctable process of logic, if the Commando street bike was the last word in vertical twins from Britain, then the Production Racer was the exclamation point at the end of the sentence. It was the fastest, best-handling, lightest and quickest Commando you could buy. A few performance figures from its era underscore the last point dramatically.

The engine had lower compression than the Dominator at 7. However the design produced excessive vibration at high revs, so the compression ratio was reduced. Electrics were 6-volt and it had Roadholder forks, adjustable Girling rear shocks and a slimline Featherbed frame. In the Atlas was upgraded to volt electrics, and gained a second carburettor and wider fork yokes. A UK version was launched with flat bars and twin instruments. The Atlas continued to be built until but by then the Norton Commando had taken over.
Specialist tuners such as Dunstall produced Atlas-based racers Domiracer and offered race-styled roadsters Dominator although later on Dunstall also designated his roadsters as ‘Domiracer’.
