My bike can do 300kph...

...yeah right! Unless your name is Choppa and you have been gifted a s1000RR!

Was browsing through trademe when i saw a listing for a "genuine 300kph sports bike" and wondered to myself how fast these bikes really go.

Shame about the ones that blew up doubt they would have got any closer.

Probably a repost. Don't really care

All off the latest jap 1000's will do near enough to 300k, and some a bit more if the 300k limiter was removed - for instance if the bike has a 5%( or more on some )speedo error which most modern bikes have then when the 300k limiter is hit you will "only" be doing a real 280-290k.
(only280-290k) haha
Remove the limiter with a plug in TRE etc and they will get alot closer to 300 and maybe a little over.

Read the article: - How the hell these journo's etc seem to blow up so many bikes is beyond me, r1 shit its pants, so did the gsxr - yet thousands of people all over the world race these bikes, drag them( and give them death) and they dont even one fault a bit. Makes you wonder what some of these journo's are doing....

Most of the tests ive seem in Performance bikes, rapid bikes etc put most of the jap 1000's top speeds at 181-187mph (292-301k) in bog stock trim.

Read through the thread i posted and it explains why some bikes had a hard time. They were full throttle for over 10 minutes!

**slofox** · 21st July 2010, 11:35

Hey - shit! I gotta try that on the 6 hunny...

**Logpot** · 21st July 2010, 12:02

Very interesting.

Now to track down some track footage of the resulting carnage.

**bogan** · 21st July 2010, 12:08

fuck thats brutal, no surprises that the honda didn't shit out though! running WFO for extended periods of time is always gonna take its toll though, not really surprised some of them blew.

My 1953 Ariel 350cc "Red Hunter" would stay at full throttle for two hours at a stretch and never turn a hair. Mind you, it wasn't exactly a high performance road rocket...

I found the comment about special tyres interesting. I was under the impression (especially for Europe) that manufactrurers were not allowed to ship a "vehicle" without a tyre spec'ed to handle it's top speed.

Consequently some vehicles have speed limiters to allow lower spec tyres to be fitted.

Probably more due to the fact it puts so much load on one side of the tyre for so long.

Great article thanks.

Braking stuff is very interesting... the top bikes are braking at pretty much exactly 1g force. I would like to see what tyres each bike had.

Wouldn't even ruffle YOUR hair.

Shhhhhhh...don't tell them that - most of these young blokes prolly think it was a demon speed machine...

Top speed was all of about 100 - 115km/hr I would guess. Never could tell because I had put a non standard speedo on it to pass a warrant. The reading was totally random and bore no relationship to actual speed as far as i could tell...

I rode it from Christchurch to Timaru and held it wide open all the way. Just kept going...

Hell, when I stripped the engine down I discovered someone before me had put the crank pin in backwards so that there was NO positive oil feed to the big end - just whatever splashed up from the crankcase. But it still went...amazing machine in it's own way.

**Big Dave** · 21st July 2010, 17:39

Yea - I destroyed a SR500 between Byron Bay and Sydney in 1978-ish. Melted the oil ring.

**Urano** · 21st July 2010, 19:23

interesting, thanks...

by the way... nardò is not in sardinia, it's in puglia, lowest east end of italy... gmaps is pretty simple to use nowadays

true.
but "zr" or "w" or "y" coded tyre are not impossible to find out, even if the cost will rise.
this will not affect a thing related to the bike. even if somebody would like to actually limit the top speed it would be sufficient to put a 1 more teeth sprocket.
easy to do, easy to change.

some factories simply register a lower top speed on the papers: "top speed: 280kmh." even if it can make 290, relying on the testing differences, and the fact that tachometers as tyres have tolerances...

about the results, remember that japanese factories have a gentlemen agreement not to make bikes that go faster than 300 kmh, so those data don't surprise me...

afaik, nardò ring was designed calculating the exact centrifugal force generated at various speeds, and making a precise rising tilt of parabolic curvature of the track.
this should allow the vehicle to remain on the lane of that particular speed without steering input by the driver, simply balancing the centrifugal and the gravity forces.
so it should be like an endless straight...

then a little consideration: the abs line is simply stupid. 2 meters more from 250 kmh is nothing at all, and remain the simple consideration that the abs will ALWAYS brakes at its maximum possibilities, human riders would not. so i am for the abs.
