Dry weight.
Good post, Bim.
The Japanese like using dry weight, which is not the test weight for the bikes but a completely dry weight - no coolant, no acid in the battery, no oil in the sump, no brake fluid, etc. Nice way for a bike to run 
The funniest thing with the R1 when it was launched was that it advertised a wheelbase figure that was really short to show off how supposedly 'nimble' it was. That wheelbase figure was only achievable with the swingarm at full droop (and the shock taken out to get it there...) and the forks pulled up through the triple clamps until the tyre hit the radiator!
Similar story with the R6 from 2003(?) claiming a 17000rpm redline (who cares where it revs, it's how it revs!...but anyway) they got caught when the cut-out what chiming in somewhat below that. But I never listen to Journos as to how a bike performs. Ever. One year the YZGSXCBR999SPS will be the best ever, the next upgrade, they will list its terrible faults and how the new one is so much better. And that's from the ones that can actually ride a bit....
I completely agree on the R1 usable performance compared with 996, but an R1 can be easily set up to match a Duke of that calibre (OK maybe not an SPS...
) for comparatively little - get some proper light wheels, some decent tyres, and actually get some springs that match the rider. It still amazes me that people will spend $$$ on a carbon fibre fairing but still run standard suspension on a bike. The rider accounts for over half the weight of some of those bikes (depends on rider and bike....)....and they expect standard suspension to do a good job? They'll get their bike dyno'd but never even try to do basic 30 minute stuff like setting the sag up correctly??
In any case...the most fun is going to track days and annoying people whose titanium Termignonis cost more than my entire bike. Going around the outside of big four-strokes and buzzing them with a lawnmower engine.

Specs...
By: BDLJ : April 8th, 2012-19:35
Components can be 'built-to-print', can they really replicate an original? I'm not so sure, but it's even more difficult to assess a system by looking at a single component - witness the discussion of Brembo brakes in another thread. Yes, opposed piston c...
All good points, TM.

Going back to the 'original point' concerning production tolerances.... A good way to think of it: Take a tolerance of 100mm +/-0.5. This tells you that it can be 99.5mm to 100.5mm. But you probably need some experience and study to know what exact length...
In general the specs are off
By: ED209 : April 8th, 2012-20:19
Interesting topic TM and would like to know more about what recent experiences have brought this up. The HK example would be a really good reason for the argument of specs/tolerences being off compared to the licensed versions (Greek for SAR8, Pakistan fo...
Sales brochures ...

Thomas, this thread could be endless ... so i will try to tell only what sticks to my mind best ... . Sales brochures of modern sports bikes that is. I started riding in the early 90ies, and in 1993 i bought a Honda CBR 600 f2 imported from the US to Euro...

this is an automotive forum afterall, and not Belles Lettres... (aside - I've found that, in general, car, and even more so, motorcycle, guys, tend to be pragmatists, at least in terms of priorities with MEASURABLE benefits like performance figures and re...

Late to comment but have read thread in its entirety. IMHO, tolerances achieved by robots are so close in modern manfacturing that BMW's from Germany, South Africa or Spartanburg would be near identical in tolerances. I no longer hear or read about bluepr...
Blueprinting.
By: BDLJ : April 10th, 2012-23:42
You're completely correct re Blueprinting and modern specs. That whole exercise of getting conrods and pistons weight matched is now done pretty well by the factory. There a no longer wierd bits of casting to get your grinder on, nor badly mismatched port...
Speedo error...
By: BDLJ : April 11th, 2012-23:53
....Speedometer errors are definitely vehicle dependent, while the error is always postive (speedo cannot under-read), brand new tyres running at decent temperature (and hence above cold pressure) will compensate somewhat for the error. If the manufacture...
