TWO STROKES ARE NOT OUTLAWED! There are no laws or anything of that nature to prohibit them from being used in a series, and as far as I'm concerned they are the answer to this modern 4 stroke fiasco in GP racing. How many times have they had to alter policies and rules during the 4 stroke era? Countless times. 2 Strokes made motoGP what it is and they belong in the series. If you want to see thumpers then watch World SBK. By the way I love World SBK but 2 strokes have their place in motoGP.
@eppsislike this is the last year of motoGP. next year they are allowing production based 1000cc motors, and allowing the production based guys to run more fuel. so essentially, motoGP is morphing into WSBK, the only difference being the hand made chassis at this point. its over, boys. and if you want to thank someone, thank honda, they were the ones who pressured FIM into outlawing 2 strokes in ALL classes, to aid them in their four-stroke r&d. they did the same to the AMA in motocross.
@MetricHotrodsdotcom It's still going to be Motogp, this is just the last year of the 800 era, I'm happy yet I'm a bit nervous how these new rules and reguations are going to pack out.
I'm just very upset the FIM took a note from Honda and moved from the mighty 2-strokes to the silly 4 strokes (have to admit though, 990's was a radical era) but still, Motogp is slowly dying.
@MetricHotrodsdotcom what a total load of garbage. Claiming rule teams have nothing to do with "morphing into WSBK", it has more to do with filling the grids. 2 strokes were outlawed because of the emisions rules. If it wasn't for motogp, cutting edge technology wouldn't trickle down into the sportbikes we ride on the roads.
@rjd560 what about the HESD on the fireblade . first used on the rc211v . varied electronically . but mechanicly the same . and hrc ecu you can adjust it
@paezbak You're wrong, pistons are made of aluminum, sleeves are steel. The pistons expand faster than the sleeves causing wear on the piston and rings. Causing an eventual loss of compression. Multigrade oils usually have sufficient viscosity to lubricate cold. Race motors HAVE to be warmed up. F1 motors HAVE to be warmed up before you attempt to even start them.
@yoGOES The motogp bikes cost like 1 million dollars... There is a company now that has developed a motogp racer for the general public. Forgot the name of the company but the bike will set you back 600.000 dollar :)
@yoGOES The Repsol CBR is not a GP replica (not even close). You can't buy a GP bike as they are prototypes built specifically for racing. The CBR is a street bike that can be raced.
you can't say this bike is better than the other one... these two bikes are like two different planets. the RCV is a hightech prototype racing bike ... only for race. its like a formula 1 car with two wheels. you will not find any parts on this bike you can buy.
the CBR is a streetbike, you can go to your honda dealer and buy a CBR without any problems if you have the money to buy it. but if you go to your dealer and say " hey i got 20k bucks, sell me a RCV Motogp bike" he will just laugh at you
@a2birdcage i think that the motogp calss has 850cc. and they are going to have 1000cc in 2011. MotoGP classes 2009: 125cc: 2 strokes, 27 riders, 17 teams. Moto2: 600cc, 4 strokes, 39 riders, 25 teams. MotoGP: 850cc, 4strokes, 17 riders, 10 teams. (stand of 23.september 2010)
@TheKristijanF BZZZZ! WRONG! The current premier class bikes are 800cc. They won't switch back to 1000cc until 2012. Next year (2011) will be the final year of the 800's.
lol that sounds so ridiculous. Metal expands when hott dumbfuck. Thats why when you are pressing crankshaft back into crank cases, you put the crank in a bag, the put the bagged crank in the freezer, then the crank cases in the oven. Then the crank drops right in without even having to press it in. Metal expands when hot, contracts when cold. the engine block needs to be cool and the piton needs to be bhott, so the block/ cylinder doesnt expand with the piston. YOU are dead wrong. dumbass
I think the main reason why we always have to warm up the engine first is because you need to get the lubricant to the right working viscosity(by increasing its temperature) so that it can reach the part it is intended to reach therefore to lubricate them and avoid the engine from unnecessary wear and tear.
Piston ring has the least thing to do with warm up. It was built to precisely fit into the cylinder. a piston has at least 3 layers of ring. Compression lost is only for cases of worn ring.
@paezbak yep, that's one thing, and as we all know, the material will grow a little bit when it get's hot, so you have to warm up the engine, that everything fits just perfect together. if you just start it cold and get out on the track and put it to the limts, some damage may occure at the valves, pistons.... whatever.
the lubricants nowadays have good viscosity at roomtemperature, nearly like water...(synthetics)
Maybe they're just testing the enginesetup at higher temperature...FI-system ect
Yea, The motor is more powerful when warm, because when the piston expands in the cylinder it presses the rings tighter against the cylinder walls and there is less ring blow-by, which in turn results in higher compression which the 4 stroke engine FEEDS on. At idle it still gets oil, but there is definitely less oil going to the top end, which is why when breaking in camshaft bearings and bedding the cam in a DOHC and the UNI-Cam design, you run the motor at around 3k for optimal lubrication.
This comment has received too many negative votesshow
fasterthanyou22(not) You don't know what you are talking about. Metal contracts when hot not the other round as you said i.e. expand. Engines generate more power at lower temperatures, but still warm temperatures.
And what happens to an oil pump's pressure when the engine is revved? You no fuck all. A "Tech" are you?? Maybe you should learn about the "Mech" you thick twat. Had a little brain fart didnt you?
Engines components warm up at different rates and therefore expand at different rates too. The valves expand quickest as they are in contact with the exhaust gases, the cylinder head warms up slowest. Warming the bike up like this will ensure everything is warm before its thrashed. Helps if you dont want the engine seizing mid corner....
cold natured racing motors. No starter motor means they have to keep the thing running. These motors have such high compression that each time they start/kill the motor, it cause unnessary stress on the engine internals. Plus the camerea was taping. Bitch.
There is no real reason why this machines are revved like this. But it probally comes from the two stroke era. A two stroke is revved like this so no oil can get clogged up at the crank. And also, a two stroke has the tendancy to choke when it's revved from idle to full throttle. The on/off revving prevents that at the start.
TWO STROKES ARE NOT OUTLAWED!

running at idle doesnt force the oil into the top of the engine so they blip the throttle.
