D O O G S I T ‘GREA E H T S I G & BI ’ S K C O L BOL WORDS & PICS: CLINK LAUNCHED IN 1998 THE YAMAHA YZF-R1 WAS A SPORTS BIKE THAT TOOK A SMALL BACKWARD STEP IN CUBIC CAPACITY FROM THE THEN CURRENT OVER ONELITRE NORM AND A LARGE STEP FORWARD IN CHASSIS RETHINKING IF NOT OUT AND OUT DESIGN. While the other three Jap manufacturers had continued to stick with the conventional transverse inline four-cylinder DOHC layout that was still recognisable from the days of the Kawasaki Z900, Yamaha had trod a different path down the same road with the forward slanting FZ750 engine since 1984, a format that also pioneered 5-valves per cylinder and downdraft carburettors. 062/152/ STREETFIGHTERSMAGAZINE SF152.ROARINGTOYZ.indd 1 23/8/06 12:16:32 pm D STREETFIGHTERSMAGAZINE \152 \063 SF152.ROARINGTOYZ.indd 2 23/8/06 12:16:45 pm “NONE OF THAT RACE-BRED TECHNOLOGY REALLY MATTERS VERY MUCH WHEN YOU GO AND STICK A FOOT LONG OVERSTOCK SWINGING-ARM AND A 300MM SECTION REAR TYRE IN IT...” The R1 also had an engine format that also allowed the motorcycle to have a relatively short wheelbase, the engine itself being considerably shorter than a convention upright transverse inline four due to the fact that in the traditional motorcycle inline engines the crankshaft, gearbox input and output shafts are parallel in a flat plane, while within the Yamaha engine with its 45-degree forward sloping engine the shafts form a triangle. Having successfully pioneered the sloping engine layout with its 5-valve heads, downdraft carbs (in addition to later refinements such as the EXUP exhaust valve), someone at Yamaha had the bright idea to stick this new 6-speed, 998cc 150bhp motor (that was also 23lbs lighter and 3.2in narrower than the existing 1003cc YZF1000 engine), into a chassis that was the size and weight of a contemporary 600 rather than one befitting a one-litre motorcycle. Thus the R1 was born and it kept Yamaha at the front of the pack for near enough the next five years before the opposition caught up with their own lighter, brighter 600-sized contenders in the one-litre arms race. But as if to counter the likes of the Suzuki GSX-R1000 and Kawasaki ZX-10R that were launched in 2003 and 2004 respectively, Yamaha fitted the R1 with an innovative fuel injection system in 2002 that worked similar to a normally aspirated intake operation by employing a CV carburettor slide controlled by vacuum created by the engine, and although the power output remained much the same a new more efficient cylinder head, a lighter crankshaft and a new exhaust featuring a twin EXUP system allowed the engine to rev higher, faster and for longer. And if that wasn’t enough the 2004 R1 had an all-new engine with 20 more ponies, a ram-air system that actually increased the BHP at high speed and a close ratio gearbox that would propel the bike to 107mph in first gear for fuck’s sake... Also the lighter new frame no longer used the engine as a stressed member and ran over the engine as opposed to around it, while the latest ‘06 model has 183 nags at the crank, a longer swinging-arm and some MotoGP inspired mods to the frame to increase rigidity. Although none of that race-bred technology really matters very much when you go and stick a foot long overstock swinging-arm and a 300mm section rear tyre in it... Hard on the heels of the Hayabusa in the mine’s-bigger-than-yours competition that typifies the current custom sport bike trend in the land of the free and the home of the mighty Yankee dollar; the louder the paint, the shinier the chrome, the bigger the rear tyre and the farther your arse is from the rear wheel spindle the more likely your efforts will be appreciated by the sort of people who think that bigger is always better. Bob Fisher is an AMA racer who appreciates what it takes to make a motorcycle behave itself at 180mph on a racetrack, but at Roaring Toyz he builds bikes that cater to the contemporary fad for lookin’ good on a race rep as opposed to riding it fast enough to scare yourself shitless. While Bob knows that the loooong swingingarm and fat tyre scenario effectively castrates a finely tuned adrenaline pump like a Yamaha R1, when the people with huge amounts of disposable income are lining up outside his door to have their bikes chromed, lengthened and fitted with a rear tyre the width of a wildebeest’s arse, he’s hardly likely to try and talk them out of it now is he? Building houses in Florida is a profitable business because every couple of years a hurricane blows them all down again, so when contractor Mark Sollitto commissioned the boyz at Roaring Toyz to do the business on his 2004 Yamaha R1 he didn’t just want a quick paint an’ polish with a mile long swinging-arm poked in the back - nope Mark wanted a full cosmetic rebuild, million dollar paintwork and a mile long swinging-arm poked in the back. And this is what he got, a full house custom job that’s just about a long as one and cost nearly as much. The entire bike was stripped down to the last Nipponese nut and bolt (‘cept for the motor), and everything that wasn’t destined to be custom painted or made out of rubber was chromed, yep shiny, shiny C2 everywhere, even the windscreen - that also doubles up a handy mirror for checking your just-off-the-bike doo before swaggering into the burger bar. A coat of what the paint guru, Ryan Hathaway, at Roaring Toyz calls ‘true flames’ was expertly laid over a red candy base to compliment the much chrominess on the rest of the bike along with a few RT billet aluminium (and chromed), accessories such as the adjustable sidestand (as the bike is 3in lower than Yamaha made it), trick flamed pattern mirrors, handlebar grips and chainguard as well as one of 064/152/ STREETFIGHTERSMAGAZINE SF152.ROARINGTOYZ.indd 3 23/8/06 12:17:18 pm SF152.ROARINGTOYZ.indd 4 23/8/06 12:18:01 pm
