Yes they are i recently went to a bike show and i saw alot of nice rides. I ride a cruiser and sometimes wish i owned a sport bike but they are really expensive to own in quebec.

You dont need a brand new sports bike bud. You could always buy something from the 90's they still go bloody quick.

Just a thought
 
Factory riders clash in Goulburn's opening Superbike race.

Three red flags have caused a rescheduling of Wakefield Park’s opening round of the 2016 YMF Australian Superbike Championship presented by Motul Pirelli this afternoon.

Race one took off at 11:55am, however the first pair of red flags came via early incidents in turn 10. It was a dramatic third red flag that caused the complete rescheduling.

Factory trio Cru Halliday (Yamaha Racing Team), Ant West (Crankt Protein Honda Racing) and Mike Jones (DesmoSport Ducati) were all involved in a first/second turn clash upon the final restart.

It’s understood Jones and West initially made contact before Halliday was struck in the aftermath, causing all three to crash awkwardly. Halliday and West remounted to return to the pitlane, while Jones had to be brought back by the pick-up crew.

All three are fine and plan to line up when race one is rescheduled directly following the lunch break, however Motorcycling Australia officials are currently investigating the incident – the cause of it potentially disallowed to restart.

Update: It’s been deemed DesmoSport Ducati’s Mike Jones was the cause of the final red flag and he will not be restarting Superbike race one coming up.

Feud Over? Rossi & Marquez To Produce Line of Handbags
by staff
Friday, April 01, 2016

Suddenly the long-simmering feud between MotoGP riders Valentino Rossi and Marc Marquez appears to be over. The news broke today in Argentina when the pair announced that they will cooperate to produce and market a line of elaborate handbags featuring their competition numbers--46 and 93.


"So, yes, this is something that I think about on the long flights here and also speak about with my friend Andrea Iannone on these flights. We think it is good idea for Marquez and me to make these bags to sell to the fans," Rossi said.

"Yes, I had to sit next to Valentino on the plane again," a sheepish Iannone confirmed.

Rossi's representatives said that the top of line 46/93 handbag will be pocket-less. The "Sepang" model will come with a heavy duty strap, which has been designed to withstand the bag being flung about and used as a fairly pathetic weapon. If, for example, two old women have a disagreement in a public square somewhere and start striking each other with their bags.

Reached for comment, Marc Marquez said, all with a bewildered look on his face, "Ahhhhh .... what? I just walked in here... and what? The last I heard Phillip Island was the best race of the modern era."

Pricing and color choices for the "Sepang" bag and others will be released soon.

Engine Math: Is the Modern Four Stroke GP Bike a Sham?

Honda RC211V..200 Horsepower?

Horsepower = Torque X RPM/5252.

The above mathematical definition describes power, as do other definitions such as Watts, as a function of force and time. The 5252 ‘horsepower constant’ is the rounded value of (33,000 ft·lbf/min)/(2π rad/rev). It also shows that Horsepower is equal to Torque (expressed in FT. LBS.) at exactly 5252 rpm. The torque, or twisting force, of an engine is the result of the additive value of the strength of all of the individual power pulses of the cylinders. The number and strength of the power pulses that an engine makes over a period of time determines how much power is being developed. The displacement, or swept volume of all the pistons, is the main determinant of how great the strength of the power pulse will be. The significance, in terms of power production, of ‘pressure wave’ tuning devices and techniques is roughly similar in both two and four stroke engines. Thus, it would seem to be sound reasoning that the four stroke engine would have to be twice the size of the two stroke to produce comparable power since it produces a power pulse only on every other revolution.

But there has been a neat trick played here. The mathematical slight of hand that the sanctioning bodies have used to rid the racing world of two stroke engines is related to engine rpm. To reason that power equivalents are simply twice the displacement for four strokes is an error. Allowing the four stroke twice the displacement as a measure of equivalence is only valid at the same rpm as horsepower is function of time. Giving four strokes twice the displacement PLUS 35% higher rpm is a lie. These are not equivalent power potentials, from a mathematical consideration. They also let four strokes run 5 cylinders in the beginning as well. They declared the two stroke illegal in MotoGP the same year they lowered the displacement of the four stroke to 800cc...which is the power equivalent to the 500 two stroke, taking rpm into consideration. They well knew that all the teams would go right back to two strokes if they let the 800 four run with the 500 two stroke. They have the same power output but four strokes are very heavy, have greater rotational mass and they carry the weight high which results in a worse handling motorcycle. Another thing to mention is that four strokes came into GP racing already sporting traction control. 18,000 rpm four strokes are not the least bit more rideable than the 500 two stroke. Nor are they clean engines either. The valve overlap necessary to run an engine at 18,000 creates about as dirty of an engine that you can make.


One need not be some tinfoil hat wearing conspiracy theorist to believe that Honda was bringing more than their claimed 200HP with the RC211V in 2002. Honda’s own CBR954RR stock streetbike was making 154HP. And the 211V had an extra cylinder, four extra valves and 60% higher rpm. Honda had been building GP engines with over 270HP per liter at 20,000 rpm since the ‘60's. Referring to traction control euphemistically as ‘power management’ fooled more than a few people but if we agree that the racer’s primary skill is to manage traction, then all of the electronic aids are, in essence, ‘traction control’.

Honda NR500. Playing by the rules is frustrating when you have an inherently flawed idea.
Honda, more than any other manufacturer, had been unsuccessfully trying to bring four strokes back to GP racing since the ‘70's, creating ever more complex contrivances such as the oval piston NR500. Considering the existence of a thriving Superbike scene, Honda’s fixation on building four stroke Grand Prix bikes is puzzling. A professional developmental class for the four stroke streetbike had existed since 1976 in the US. And the World Superbike class’s inaugural season was 1988. MotoGP has become a redundant class with their current hardware. But seeing how the political climate of the time was changing Honda jumped at the opportunity to add weight and rotational mass to racing bikes.

Yamaha’s new business plan: Who needs the rider?
The current MotoGP racing scene is still quite good despite the fact that the bikes are doing much of the riding themselves. The quality of riders such as Rossi, Lorenzo and Marquez is impressive, to be sure. But a big part of their development as riders might have come from racing two stroke bikes. Younger riders may not prove to be anywhere near as capable as they are racing bikes that are simply easier to ride. We’ll see.

Termas de Río Hondo – Grand Prix racing in Argentina


Valentino Rossi celebrates in Argentina (2015)

MotoGP returns to the Termas de Rio Hondo circuit for a third year, and below are a selection of facts and stats related to this event.

  • This year’s event at the Termas de Rio Hondo circuit is the 13th motorcycle grand prix to be held in Argentina.
  • The first Argentinean GP took place in 1961 and was held in Buenos Aires; the first time that a grand prix had taken place outside of Europe. Not all of the top riders attended the event and the 52 lap, 203 km, 500cc race was won by home rider Jorge Kissling (Matchless) from fellow countryman Juan Carlos Salatino (Norton).
  • This is the third year that the Argentinean GP has taken place at the Termas de Rio Hondo circuit. All of the ten previous grand prix in Argentina had taken place in Buenos Aires, the last of which was in 1999.
  • Three riders from Argentina have won grand prix races; Sebastian Porto (seven wins in the 250cc class), Benedicto Caldarella and Jorge Kissling who both had single victories in the 500cc class.
  • The last GP win by an Argentinean rider was in the 250cc class at the Dutch TT in 2005, when Sebastian Porto won the race from Dani Pedrosa and Jorge Lorenzo.

Sebastian Porto – 2005

  • In 1962 the 250cc GP in Argentina was won by Arthur Wheeler at the age of forty six – the oldest rider to win a grand prix race and the last of Moto Guzzi’s forty five GP wins.
  • In 1963 Mike Hailwood raced in Argentina for the first time on the factory MV Agusta and dominated the 500cc race by lapping all other riders and finishing six laps in front of the rider finishing in sixth place.
  • The only current full-time grand prix rider who has raced in grand prix at the Buenos Aires circuit is Valentino Rossi, who won the 250cc race in 1998 & was third in 1999.
  • Last year in Argentina Danny Kent won the Moto3 race, Sam Lowes was third in Moto2 and Cal Crutchlow third in MotoGP, the first time that Britain has had podium finishers in three current GP classes (or equivalent) at a GP event since the British Grand Prix at Silverstone in 1978.

Danny Kent became the first British rider to take back-to-back wins in the lightweight-class since Barry Sheene in 1971 when he won in Argentina in 2015

  • Johann Zarco won in Argentina last year – his first race victory in the Moto2 class.
  • The six grand prix races that have taken place over the last two years at the Termas de Rio Hondo circuit have resulted in six different winners: Moto3 – Fenati and Kent. Moto2 – Rabat and Zarco. MotoGP – Marquez and Rossi.
  • The two MotoGP races in Argentina have resulted in six different riders finishing on the podium.
  • Valentino Rossi is the only rider to finish in the top four in both MotoGP races that have taken place at the Termas de Rio Hondo circuit; fourth in 2014 along with last year’s victory.

Great opening race of the season for the World Champion
Jorge Lorenzo opened the defence of his world title in Qatar in great style, as illustrated by the following facts and stats:


Jorge Lorenzo

  • He qualified on pole, won the race and also set fastest lap; this is the seventh time in the MotoGP class that he has achieved this.
  • Lorenzo became the first rider since Casey Stoner in 2009 to win the opening race of the year having won the final race of the previous season.
  • Despite the changes to the electronics and tyre manufacturer Lorenzo improved on the record race time set last year by more than seven seconds.
  • In Qatar Lorenzo started from pole for the 62nd time in grand prix racing across all classes, which is the greatest number of poles among current riders, one more than achieved by Valentino Rossi.
  • This was is the ninth successive year that Lorenzo has had a least one win in the MotoGP class. Only four other riders have scored wins in the premier class for nine or more successive seasons: Giacomo Agostini (wins in 12 successive seasons), Valentino Rossi (11), Dani Pedrosa (10), Mick Doohan (9).
Twenty-five successive point scoring finishes for Bradley Smith

Bradley Smith

Bradley Smith’s eighth place finish in Qatar was the 25th successive race at which he has scored points. The last race at which he did not finish in the top fifteen was the British GP in 2014 when he had to call into the pits due to a faulty rear wheel. As shown in the following table this is one of the longest sequences of successive point scoring finishes in the history of the premier-class. Among current riders only Valentino Rossi has a longer sequence of successive point scoring finishes:

Longest Successive Point-scoring Finishes in the premier-class
  • 37 Mick Doohan (Italy 1995 to Indonesia 1997)
  • 34 Colin Edwards (Qatar 2004 to Malaysia 2006)
  • 30 Wayne Gardner (West Germany 1986 to West Germany 1988)
  • 28 Eddie Lawson (Italy 1983 to Yugoslavia 1985)
  • Valentino Rossi (Portugal 2002 to Dutch TT 2004)
  • 26 Eddie Lawson (Great Britain 1987 to Brazil 1989)
  • Valentino Rossi (Catalunya 2013 to San Marino 2014)
  • 25 Jorge Lorenzo (Malaysia 2009 to Catalunya 2011)
  • Valentino Rossi (Germany 2010 to Aragon 2011)
  • Bradley Smith (San Marino 2014 – ongoing)

MotoGP Statistics 2016 – Argentina MotoGP – Longest successive points scoring finishes

Grand Prix racing numbers
  • 2000 – The sixteen points scored by Marc Marquez for finishing third in Qatar took him to a career total of 2000 points across all three classes. He is just the 13th rider in the 68-year history of motorcycle grand prix racing to reach this milestone.

Marc Marquez, Andrea Dovizioso, Valentino Rossi

  • 56. 236 seconds – Marco Melandri, who finished in 20th place in Argentina last year, finished just 56.236 seconds behind race winner Valentino Rossi. This was the first time in the 67 years of motorcycle grand prix racing, in a race that has gone full distance, that the first 20 riders across the line in a premier-class GP have finished within one minute.
  • 40 – The third place finish by Marc Marquez in Qatar was his 40th podium in the MotoGP class – the same number of premier-class podiums that double 500cc World Champion Barry Sheene achieved during his career.
  • 30 – Andrea Dovozioso’s second place finish in Qatar was his 30th podium in the MotoGP class – the same number of premier-class podium finishes as Sete Gibernau. One more top three finish for Dovizioso will take him level with Freddie Spencer in terms of premier-class podiums.

Andrea Dovizioso

  • 29 – Julian Simon celebrates his 29th birthday on race day in Argentina.
  • 17.608 seconds – In the Moto3 race in Qatar, Malaysian rookie Khairul Idham Pawi finished in 22nd position but crossed the line just 17.608 seconds behind race winner Niccolo Antonelli. This is the smallest ever margin covering the first twenty two riders across the line in a full length grand prix, taking the record from the Moto3 race at the Dutch TT in 2012 when the rider finishing in 22nd place crossed the line 21.581 seconds behind the race winner.
  • 6 – Maverick Viñales finished sixth at the Qatar Grand Prix – the best result at the Losail circuit for Suzuki since John Hopkins was fourth in 2007.

Maverick Vinales

  • 5 – The Termas de Rio circuit is one of just five venues on this year’s schedule where Jorge Lorenzo has not had a win in the MotoGP class, along with Austin, Sachsenring, Sepang and the new Red Bull Ring in Austria.
  • 3 – At the Qatar Grand Prix, Italy had a rider finish on the podium in all three classes for the first time since the San Marino Grand Prix in 2012.
