Maaaad.

Bet that thing is almost unride-able. Bit crazy tbh, could bet a standard S1000rr would be such a nicer ride.

Still, impressive engineering I suppose.

That's a lot of power, but I reckon my bike could beat that figure. One day I'll find out

That is some serious poke, however you'd probably need a 10 meter long swing arm just launch it off the line properly

Was just wondering there watching it how a chain like that handles 500+ ponies

Cos chain all flappy then tight n stuff innit.

Think I was trying to ask if you drag strip people take that into account when you add xx" to the swingarm. To my inexperienced eye it looks like the chain could foul on something...or come off.

My thoughts too: Where do you get a chain that's designed to take that kind of power?

Sod it, I'll just use a clip link to fit this.....

In fact, where do you get a chassis/gearbox/everything to take that kind of power?

No welding on a one-piece crank. The gearbox is ok for it AFAIK but the clutch is the 12r's weak point. It'll have a lockup at the very least probably a stronger basket too. Rods will certainly be aftermarket as will pistons, valve springs probably head bolts too.

This biggest down-side I can see to boosting the 12r is the barrels being integral to the top casing. If you mess up and smear a piston you can't just swap the barrels like you can on the 'busa, you have to strip the engine and replace the cases or have the bores re-worked.

Pete, does more block rigidity not make up for this though? I know that for racing use, being able to quickly strip and re-build an engine with the least amount of work/disassembly is probably a big plus factor, but I always see separate barrels as a very 90's design feature, and that by going one-piece like a car block, you can make an engine lighter or stronger maybe?

I always liked the rover K-series engine for it's method of construction, with long through bolts holding everything in tension and a big crank ladder/bearing frame and baseplate to sandwich everything together with.

Would be a crap design for racing due to the reasons mentioned above, but I've never understood why other firms who make engines out of better quality alloys and proper block/liner design have not used the long bolt system?

[Pete.]

I don't know, I guess that integral barrels does give greater rigidity but they probably use it more to add lightness. All good on a stock bike but if you're pushing the boundaries it can get very expensive.
The serious drag racers, and the ones who can afford it keep a spare built engine or two so they don't have to rebuild between races.

Any vids of it on the street or at the track?
