Anybody else download the video from Monday's WebWatch at http://home.earthlink.net/~zensur/topend_wee.wmv

It's awesome

The acceleration when the front wheel comes back down beggars belief.

Been trying to work out whether I believe the speedo. Hard to accept it was really doing 240 mph as indicated, and some other funnies like no loss of acceleration through gear changes.

Any bikers got views on this?

Wow! Fantastic!!

Pete, clutchless gear change mean anything! on a bike you don't need the clutch to go up the 'box!

Have been wondering about speedo myself, wheelie to 140mph through 3 gear changes! hmmmm!!

Impressive all the same!

I'm convinced the scenery isn't moving as fast as it should, especially when he slows down to "just" 100 at the end.

My itchy suspicious bump makes me wonder whether there's a 1:2 gear in the speedo cable...

A friend of mine said he'd done 160mph on a bike, and reported that limbs that stick out in annoying places (fact of life really) were a major problem in this regard.

Well it looks good but I don't think it is true too

The acceleration times were too good to be true, I think Marshy has it right, or perhaps a speedo from a different machine?

Gents, I think the speedo reads kph, not mph. If I stretch my eyes (what ever that means) hard enough, I seem to see a vertical first letter on the speedo, so a 'k' rather than an 'm'

Yeah... check again. If you pause the video at second 12 it seems quite obvious.

I think that the numbers are in KILOMETERS per hour, despite there being a small kmph dial. If it's an electronic speedo, then this sort of thing is possible using switches on the back of the dash(different markets, etc. etc).

Kmph would also explain why the speedo is pegged for the last 1000 revs. It certainly wasn't designed that way.

However - Multi-gear wheelies - Much RESPECT

I've just had a long look at the writing on the dial and I reckon.......

1) The outer dial is mph, inner kmph. The numbers tie up (100kmph==60mph, 160kmph==100mph, etc)

2) The writing above the center says GSX 1300R (though I really had to squint for this one).

A GSX 1300R would explain the electronic dash and the phenomenal acceleration (even with the dial read as kmph!)

Geez, Duncan you are right !!
Must say that I am dubious it really looks like Fighter-jet acceleration.

Fake guarantee it

Acceleration on a bike is not linear as this almost appears to be. i.e the 0-60 is never the same as the 60-120 and most definitely not the same as 180-240. I suspect as stated earlier the speedo is either running in the wrong way round with km / miles as said earlier or if its got a mechanical pickup either geared incorrectly or the electronic dash has been lied to about wheel circumference etc. The other point to note is that when the front wheel is in the air the speedo appears to stabilise slightly (correct) and then when it comes down accelerates rapidly (playing catch up) as mechanical speedo pick ups are on the front wheel suggesting that it hasn't been computer altered.

Umh, from 0-320 Kph 20 sec. Guy, Boneville waits for you !

Only reading that I beleive is GPS reading or professional speedo as you can see in some other photo or film. That speedo seems fake.

In the other way, compliments for the brave man who ride this missile. Even 150 Mph on bike are too much for me.

Sorry to disagree, but I think this is totally genuine. The Kph match up with the mph and I'd say the acceleration is not far off. There was a big discussion about this on the Lotus BBS. The bike is (I believe) a Hayabusa 1.3(~185 bhp, 215 Kg, 0-200 kmp in 7.6 secs) , and is quite capable of this sort of speed/acceleration especially when modified. I myself got overtaken on the motorway last summer by a biker doing a wheelie pass me at about 120 so I can totally believe this.
What HertsBikers opinion???

In truth the wheelie is not the problem it is fairly stable to hold the front wheel in the air at these speeds the problem comes because the front wheel slows down as the gyro effect diminishes then on "touch down" the tyre shrieks like an aircraft and is very prone to "tank slap". My passion for TVR's was brought about by a trip to LM cars one summer and playing with the owners on a bike en route, three of us actually overtook a line of about 4/5 assorted tiv's on a straight, 100mph plus with atleast 2 of the bikes on the back wheel (any drivers remember a similar incident?? 99 I think). It's not mythical or even particulary difficult if like me you grew up with motorcross, then road bikes, short circuit racing and then when older fatter and slower endurance racing before seeing the light realising the risks actually effect others a wife, family etc and move onto 4 wheels !

Trust me the speedo is dodgy !

Oh yes by the way I still have a ZX7RR endurance racer and a ZX12R road bike so I haven't totally quit!

Oh yes I was also with a mate who flipped an R1 at 80-90 ish (2nd to 3rd gear change) while wheelieing at junction 4? (M26 interchange) of the M25 last summer. It does happen !!!! they just don't pull that quickly to the end stop of the speedo.

I'm almost certain that this is genuine. I have a 146hp Kawasaki ZZR1100 - 0-60 in about 2.5, 0-100 in not very much more. It'll show 200mph on the speedo (although true top whack is about 180) and wheelies in second gear without any clutch intervention at all. The sense of speed when you unleash that acceleration is pretty awesome - It never fails to put a big grin on my face!

Well I haven't watched it - can't figure it out the file type? what player do I need guys?

But I would like to tell you that when I went in my mates derestricted BMW 740, which does a respectable 0-60 of under 6 seconds... that it seems dog slow compared to a 600c bike.

Obviously it felt like the fastest car I've ever been in, but still not a patch.

I lent same mate my Thunderace, then we went down the pub in his car. The first thing he said was "where's the power gone?" !! (in the car, obv.)

Tell you chaps, you may have the advantage of wet weather protection and cornering/braking, but unless we are looking at 1000bhp cars, you ain't gonna touch a "big" bike for the 0-100 sprint.

Videos may be easy to fake, but I have seen 170 on my mph speedo, and it feels like Star Trek.

Warp factor 9, engage! the world becomes a blur, and your eyes hurt with trying to take in all the visual data.

To those without the necessary license, if we ever met up, you could borrow a lid, and come out for a spin on my bike.... as long as you promise to show off your car afterwards !

respect.
