Yeah that's why it floats on water, its not a chemical thing its a mass density thing ! same for oil. Re the R6 test. PB ran a test when the new CBR600RR came out where they hid the bike from the riders & disguised it & made them get on blind folded. They used a track & most riders were faster on the CBR600F4i than on the new RR, but most wanted to own the new RR ! Go figure ;( Link to comment Share on other sites More sharing options...

Swapped cams on an R6 a few years ago so they produced a bit more torque mid range but were less in total Hp and compared it to a sets R6 model. Surprise surprise 95% of those that took part in the experiment preferred the bike that " made more power" , which in actual fact made more torque in midrange than power in top end compared to the factory bike. Which proves onthe other hand that most folk don't know what the fuck they are talking about. I was involved in that experiment, what they did was convert the latest new engine back to the previous model. This was quite an engineering feat as the architecture had changed, involved removing the cams, cutting them in half and re-joining them to change the phasing. The upshot of it all was that most liked the modded bike as it ended up with more mid range than the previous model. Ran a bit rough below 30mph though.but that is no surprise considering what was done to it. Link to comment Share on other sites More sharing options...

You're right -- and if I'd thought about it, I would have realised that must be because they're less dense. But I never did think about it. Blame my arts background. 25% is a massive difference, though. Link to comment Share on other sites More sharing options...
RVFR Posted August 23, 2017 Share Posted August 23, 2017 What a thread, love it. smh with a laugh too. You want more, like how much? the Ape Tuono might solve your need. Gee, might have to re work it in the header build to include the 8th gen Hmmmm??? Link to comment Share on other sites More sharing options...

Been there, got the Dremel. But unless you're doing sprint races at the velodrome, the only time you really notice the weight savings is while carrying the bike. On a motorcycle, saving weight up high like inside the gas tank, or in rotating mass like the wheels, makes big differences in flickability in track settings, or if you're trying to set a new record for the local "technical" roads. But you have to shave a fookin' lot if you're expecting to feel it in the seat of your pants under acceleration. Surely the greatest gain in the power to weight ratio on any machine, two wheels or four, leg powered or engine driven is for the greatest mass I.E. 'the loose nut behind the bars/wheel' to engage in some performance orientated weight loss. just sayin. Link to comment Share on other sites More sharing options...

Was at a WERA race recently and really surprise at how hefty (overweight) some of the riders were. Too many Big Macs and large fries..... Link to comment Share on other sites More sharing options...

I highly doubt I could loose 8kg from my lean & mean physique! Link to comment Share on other sites More sharing options...

It's winter atm where I am so a full textile winter jacket with back protector is probably 3kg on it's own, 1.5 for the Helmet, 0.5 for shin boots, another kilo for textile pants with armor. It add's up. Try it yourself. Jump on the scales in your regular day wear then gear up and see how much extra you weigh in gear. You'd be surprised.

As was the comment regarding losing weight from the "Loose nut behind the bars" but in my experience most of the "Weekend Warriors" who spend their time fitting titanium everything and discarding anything that might add weight and destroy their power to weight ratio, are the very people I speak of. T'aint no good losing 10Kg from the bike of the rider weighs 100kg/220lb Also 8Kg for those of the "Lean and Mean Physique" (I include myself here 6' and 13.5 stone/190lb/85Kg) rises exponentially with the increase in girth of the controlling homo sapien. Surely all the extra material needed will increase the unladen mass atop those erstwhile Race Day Rockets.. Link to comment Share on other sites More sharing options...
Audible Posted August 26, 2017 Share Posted August 26, 2017 Ah ok, I missed your tongue in cheek. I usually loose 2-3 kilo's in Summer. I'm 5ft 8 and currently 77kg, usually 75kg in Summer so I'm not that much over ideal BMI. No, really, I'm not! Link to comment Share on other sites More sharing options...
