26-475: The FZR1000 was generally regarded world's finest production sports motorcycle at that time and in its 1989 FZR1000R incarnation the engine produced over 140 hp with a class-leading handling to match. The FZR1000R won bike of year across the motorcycle press and was crowned the "Bike of the Decade" by Cycle World . The machine was continually updated throughout its lifetime and continued to collect awards through

52-552: A 40% over the equivalent steel frame.. Although first seen on Yamaha racing machines such as the FZ750 OU74 race machine and in use on other smaller capacity or racing motorcycles, this was the first use on such a large production motorcycle. Aluminum perimeter frames are now common amongst contemporary sports motorcycles. The new frame was complemented by large 41mm diameter Telescopic forks , cast aluminum hollow spoke wheels suitable for radial tyres. The 1989 redesign that resulted in

78-577: A large production road-going machine. Additionally a new wheel design with lightweight hollow spokes that were wide enough to take the latest radial tyres was fitted. The FZR1000 Genesis was presented to the public at the Cologne IFMA motorcycle show in Germany in September 1986 and went out of production following the 1994 introduction and sales success of the latest generation of SuperSport motorcycles, led by

104-715: A new era of objective journalism" to the US. As of 2001 Cycle World was the largest motorcycling magazine in the world. The magazine is headquartered in Irvine, California . Regular contributors include Peter Egan and Nick Ienatsch . Previous or occasional contributors have included gonzo journalist and author Hunter S. Thompson , journalist and correspondent Henry N. Manney III , and professional riding coach Ken Hill . Parkhurst sold Cycle World to CBS in 1971. CBS executive Peter G. Diamandis and his associates bought CBS Magazines from CBS in 1987, forming Diamandis Communications , which

130-431: A recount. Another Kawasaki was disqualified for petrol tank modifications. Two BMW teams would have placed second and third, but were disqualified for suspension modifications. Yamaha RD-350 riders Barry Lemon/David Robbins won the 500 cc class with 333 laps, followed by Kawasaki H1-500 riders Peter Stronach and Jeff Sim (331 laps) and Honda CB-500 riders Lynton Carle and Otto Muller (330 laps). 250cc class winners (subject to

156-401: Is hydraulically operated. Final drive is by O-ring chain and sprockets. The FZR1000 chassis provided the biggest advancement over the original Yamaha FZ750. A major reduction of frame weight resulted from the use of an all aluminum square section 'Deltabox' perimeter type frame. The frame consisted of cast and extruded sections, welded together and provided a large weight reduction, in region of

182-494: Is totally hand made. Originally the race was called the Castrol 1000 in recognition of the prize money on offer from Castrol. $ 1000 was a considerable sum in 1970 as can be seen by the fact that the eventual winning bike in the first race, a Triumph Bonneville 650 , could be purchased for around $ 1,150.00 at the time. At first the race was for 3 classes, Unlimited, 500 cc and 250 cc. The race continued in that format until 1975, when

208-452: The 'EXUP' bikes, provided a major refinement of the Deltabox frame, the more compact engine allowed a completely redesigned and smaller frame and along with the new 17" rear wheel and 43mm Telescopic forks . The machine was thus shorter, lower, stiffer and lighter than the previous model. The bodywork was also redesigned resulting in an almost new machine. In 1991 a further redesign resulted in

234-551: The 1992 introduction of the Honda Fireblade . The FZR1000 engine was developed from similar smaller cc motors of that time like Yamaha FZ750 with the same liquid-cooled 5 valve per cylinder (3 intake and 2 exhaust) engine layout with 45° inclined cylinder block. While somewhat superficially similar to the outgoing FZ750 unit, this 989cc engine was an entirely new design, including larger diameter valves and correspondingly larger 37mm BDB Mikuni CV carburetors. The lubrication system

260-504: The 250 cc class was dropped for "rider safety". Then in 1978 the 500 cc class was dropped and a 750 cc class introduced. For 1983 The maximum capacity was limited to 1000 cc, probably to comply with the ACCA regulations and in 1987 a 250 cc class was reintroduced. The first race was run on Sunday, 18 October 1970, when 68 riders lined up for the Le Mans start. Thirteen riders dropped their machines in

286-472: The Honda. Yamaha subsequently advertised that its 650 was quicker than nine out of ten superbikes. The 1972 race ended in controversy with Joe Eastmure initially being declared winner on a 315 cc Suzuki 350 . Two hours later Kawasaki 750 riders Mike Steele and Dave Burgess, who had crashed four minutes before the finish, were declared winners. A protest was lodged against them on the grounds that they had returned to

312-630: The bike was popular in open class racing in the hands of private teams. The bike won the Castrol Six Hour and Isle of Man TT Production class B in 1987 and the Castrol Six Hour (New Zealand) in 1987 and 1988. Cycle World Cycle World is a motorcycling magazine in the United States. It was founded in 1962 by Joe Parkhurst, who was inducted to the Motorcycle Hall of Fame as "the person responsible for bringing

338-404: The circuit without making a pit stop for a safety inspection. Eastmure's bike was later disqualified for not having a horn. He returned in 1973 riding the same bike (with horn) and placed outright sixth, winning the 500 cc class. In the 1974 race BMW R90 riders Bryan Hindle and Clive Knight were initially declared winners. Kawasaki Z1-900 riders Len Atlee and Ken Blake were declared winners after

364-467: The early 1990s. The FZR1000 was a natural development for Yamaha's Genesis design concept pioneered with the Yamaha FZ750 . The major feature update was in a new aluminum perimeter type frame, marketed as the 'Deltabox'. The frame was still in their early stages technologically, and although there was experience in using aluminum Deltabox frames on race machines, this would be its first application on such

390-425: The event since the start over eligibility of bikes or components. Also races for production bikes were losing support as more people moved to the new Superbikes . The move to Oran Park was also not popular with many fans. There have been attempts to revive the idea of a six-hour endurance race, including one at Phillip Island , one at Eastern Creek and two at Oran Park in the 1990s and early 2000s but none met with

416-472: The first four laps. Honda 750s filled nine of the top ten places in 1971. Tony Hatton and Paul Spooner came second on a Yamaha 650. The heavy and powerful Hondas were all expected to stop for tyre changes. Hatton and Spooner moved up in the placings as each Honda stopped to change tyres. They realised too late that Brian Hindle and Clive Knight were planning to finish the race without changing tyres. Despite Haton's and Spooner's efforts, they were unable to catch

442-447: The motorcycles they might wish to buy. The main character of the race being the bikes had to be stock and were rigorously inspected to ensure they were. It also had considerable television coverage and either contributed to or was the result of a motorcycle sales boom. The 6 Hour was so important to the industry, Honda designed the CB 1100R(B), to win the race. The first model had no fairing and

468-422: The new EXUP model its commonly used name was Yamaha's four-stroke power valve system EXUP valve, a servo-motor-driven exhaust valve. This allowed large bore exhaust for improved gas flow at high engine speeds but with good low engine speed performance thanks the engine speed controlled exhaust valve restricting flow at lower revs. The new EXUP machine gave class leading pulling power from low revs, seamlessly, up to

494-552: The outcome of protests) were Lee Roebuck/Jeff Parkin (Yamaha RD-250) 326 laps, followed by Vaughan Coburn/Ron Burke (Suzuki GT-250) 326 laps and Terry Brown/Paul Grayden (Yamaha RD-250) 325 laps. Kawasaki 750 rider Warren Willing was disqualified For alleged gearbox irregularities. The end came partly because of Castrol pulling out of road racing to concentrate its efforts on initially the Mr Motocross Series and then V8 Supercars, and partly because of controversy that had dogged

520-470: The red line at 11,500 rpm. It also allowed extremely radical high lift cams that gave a very lumpy idle when unplugged in the open position or when using a full aftermarket exhaust. Yamaha continued to use the EXUP valve system on the subsequent Yamaha YZF1000R Thunderace and Yamaha YZF-R1 motorcycles. The FZ1000 uses a five-speed sequential close ratio gearbox. The clutch is of the wet, multi-plate type and

546-533: The release of the FZR1000RU EXUP, upside-down telescopic forks were fitted and the front fairing was fitted with a single headlight, generally regarded to be the definitive FZR1000. By 1994 the machine reverted to twin headlights, although now 'Fox Eye' styled, braking however was improved with the fitment of six piston front brake calipers. The 1000cc engine excluded the bike from the then popular Superbike racing class which limited four cylinder machines to 750cc,

650-503: Was enhanced with a dual rotor oil pump and external oil cooler . In 1989 the machine received a major redesign, top to bottom, notably resulting in a marginal increase in capacity, rising from 989cc to 1002cc. Further, the cylinder block angle was reduced to 35°, thereby effecting a nominal reduction in wheelbase. The intake system was upgraded commensurate with these changes to include larger 38mm carburetors, as well as matching oversized intake and exhaust ports. A unique feature that gave

676-533: Was run by the Willoughby District Motorcycle Club and held at Amaroo Park until 1983, when it was moved to Oran Park for 1984 until the final race in 1987. At the time it was the biggest and most prestigious bike meeting in Australia, enjoying huge support from not only Castrol and much of the motorcycle trade, but also was a great hit with the motorcycle community who saw it as a real test of
