If you missed the glory days of when Americans dominated Grand Prix motorcycle racing, or simply want to relive the moments from yesteryear, then we have the perfect treat for you this Monday afternoon. A television production by Britain’s ITV4, The Unrideables is a 45-minute trip down memory lane with Randy Mamola, Eddie Lawson, Wayne Gardner, Kevin Schwantz, and many others.

Focusing on the racing from the late-1980′s, we get to hear the riders and journalists of the time recount their victories and defeats on the 500cc two-strone monsters of that era. It is a really well done piece by ITV4, and it is really a shame we can’t get similar programming here in the United States. A big thanks to whomever put it up on YouTube, and thanks to all our tipsters who pointed it out to us.

At the Sachsenring, after the introduction of KTM’s Moto3 GPR production racer, we spent five minutes with KTM’s Head of Motorsports Pit Beirer. We spoke to him about a number of subjects, including the evolution of the factory’s Moto3 chassis, the company’s cooperation with Kalex, and whether two-strokes would be better than four-strokes for racing.

Asphalt & Rubber is based out of California, so that means smoking is akin to a cardinal sin out here, and on the hierarchy of egregious crimes against humanity, it ranks just slightly under torturing babies with hot pincers (heaven forbid you cause a baby to start smoking). Smoking indoors in outright verboten virtually everywhere, while puffing some nicotine anywhere outside that is near a restaurant, bar, club, ATM, hospital, pre-school, or tobacco shop is liable to cause a citizen to go murder-death-kill on you John Spartan.

The issue is so pervasive here, that it has even extended beyond cigarettes and into the realm of motorcycling, with The Golden State leading the charge on the banning of two-stroke motorcycles. We are now purely a “suck, squeeze, bang, blow” society, and while that suits many motorists just fine, there are some who enjoy the smell of pre-mix in the morning — you know who you are. You enjoy the sound of angry bees following you from apex to off-camber. You think a displacement for “serious riders” starts at around 250cc. You like your engine compression low, and your powerbands narrow. You sir (or madam), are a two-stroke junky, and we have just the fix you need.

Just as MotoGP replaced 500GP, we know see Moto2 & Moto3 replacing the lower two-stroke classes that remained in Grand Prix racing. Leading the charge on this mechanical front are a slew of new companies, most notably the chassis manufacturers, of which Suter is perhaps the most well-regarded. Making the weapon of choice for Marc Marquez in Moto2 this year, the Swiss company already had a sterling reputation before it went racing at an international level, but the firm’s success in the 2010 Championship exposed it to a whole new world of tw0-wheel performance.

Having a bevy of intriguing two-wheeled projects within its walls, the Swiss bike that catches our eye today is the Suter 500 Factory V4: a two-stroke, 500cc, V4, track weapon that puts out over 200 hp and weighs 284 lbs ready to race — no, that is not a typo. We’ll let you take a moment before continuing past the jump for more.

Take one Kawasaki H2 750 motor, recently decommisioned from drag strip duty we might add, throw in a plenty of bling parts, for measure include one deliciously white powdercoated frame, and you’ve got one seriously trick bike that is sure to go “kwikasfaki” (295lbs, 135rwhp, 9.3 down the ¼ mile if you’re a numbers person). Oddly enough, that’s exactly what one member on the Custom Fighters forum, named cabbie, did (full build thread here), and the result is Pamela-Anderson-in-a-wet-leotard-on-a-windy-day stunning.

While everyone is busy trying to murder out every piece of their motorcycles with the darkest shades of dark (quick diversion: has anyone noticed how the OEMs are all finally catching onto the styling trend?), cabbie is going the other way with his design: all white everything. The result is a bright and eye-catching bike, and oh…check out those three gorgeous two-stroke exhaust pipes. We’d write more, but we’ve soiled ourselves. More photos after the jump.

Meeting this weekend, the GP Commission confirmed the demise of two-stroke GP racing as they finalized plans to start the Moto3 series in 2012. Replacing the 125GP racing class, Moto3 will center around 250cc singe-cylinder four-stroke motor with a maximum bore size of 81mm. The class will be open to multiple engine manufacturers, who will have to make their motors available for €10,000 or less.

Back when men were men, and GP racing’s crowning event was contested on two-stroke 500cc machines, Wayne Gardner found himself carrying the factory Honda GP team on his NSR 500. This fantastic 1986 documentary, Lone Racer, follows Gardner one year before he won the 500GP Championship, and became the first Australian to win GP racing’s premiere racing class.

The film includes great behind the scenes footage of the Aussie, his fiancée, and his team. So grab a cold beverage, put your feet up, and get ready to spend the rest of your Saturday afternoon watching the 30 minutes of video in this three part series. Videos after the jump.

In its stock form, the Cagiva Mito is not the most outlandish motorcycle every created. It boasts only a tiny 125cc motor, that makes barely 15hp. But when Simone Barbagallo got his on an unsuspecting Mito, the result was something quite the opposite of ordinary.

Barbagallo has increased the little elephants peak power to 90hp by adding a supercharger and NOS system to the donor bike. Not willing to call it quits, he then proceeded to bore out the motor 200cc’s. With almost no stock part left to be replaced, the result is what Simone calls, the Scorpion Performance, and he’d be willing to part with it for $55,000.

I can imagine how the converstion between Wayno and Stevo went (well they are from Far North Queensland). That is Stephen Rothwell and Wayne Wright from The Two-Stroke Shop. It’s safe to say it ended with “Let’s build the bike that should have been”.

They set about getting a 500cc two-stroke built to slip into Apilia’s RS250 frame. The RS250 is an excellent bike. It’s good looking, has great handling and will stop on a dime. But! There’s always a but. In standard trim it’s powered by a Suzuki RGV250 engine. Not that the engine is all that lacking and can still scare most people, this bike with a 500cc 2-stroker now becomes a capable weapon ready to tackle modern 4-stroke sport bikes.
