  1. I watch the motoGP as I enjoy the skill of the riders, as I do with the TT. The politics of motoGP and probably most pro-level motorsport leaves me cold and I think the results are skewed towards the riders with the best platforms, so I think 2016 (control ECU etc.) will provide a slightly more level playing field will produce tighter racing. The moto2 and 3 classes produces a much better racing spectacle. I agree with the OP that sometimes the recorded sound of the GP machines is buzzy and grating. Never heard them live though.. Those TT racers - that does take the right stuff..
  2. I don't know what you're talking about. I ride my superbike in an entirely lawful manner, your honour... I run my street tyres similarly - above track pressures but I do bring the rear up quite a bit. I suspect running the much lower track pressures common on rear tyres like the Supercorsa will lead to potential rim damage and fast tyre wear on your average street and country road asphalt... I still wonder about the reversed polarity between front and rear pressures for track vs street recommended by the tyre and bike mfgs....
  3. Ok. I'm reading that under-inflating the front can lead to steering issues, for a variety of reasons - a wider contact patch in front leading to understeer makes sense. So, here's my next question - why doesn't the higher inflation of the front hold true for street riding? It seems the bike manufacturers (who presumably test their OE tyres extensively) recommend a higher inflation rear even without pillion. Take the Pirelli Supercorsa SP for example. The current Pirelli tech recommendation for track riding is (cold) 23-26 PSI rear (180/190/200) and 30-32 front (for a 120/70). However, on my Panigale which uses the same tyre as OE, Ducati recommends a front tyre pressure of 30.5 to 31 PSI and a rear tyre pressure of 32 to 32.5 PSI. I see BMW recommends a higher rear/lower front for the S1RR (or at least on the one I looked at). I understand the reason for generally higher tyre inflation on the street - less chance of rim damage, etc. but it still doesn't explain the reversed front/rear inflation thing-o..
  4. I similarly thought a 200 rear would make the bike a bit more difficult to turn in, as opposed to a smaller section tyre like a 190. This has been one of the complaints about the Ducati Panigale, which runs a Pirelli Supercorsa SP 200 rear as OE (I ride one) and I've found that the S1000RR was quicker to steer, despite being heavier.. Still, I'm no expert...
  5. Thanks rchase. I don't know if I'll ever get to pick Nate's brain as I'm down here in Australia but I'll certainly remember it if I'm ever up your way. I see the DDC-optionable 2015 S1000RR will be running the 190/55 supercorsa rear. More generally, I wonder how the supercorsa tyres, whilst brilliant in the warm/dry will perform in the cold/wet. I wouldn't be that keen on riding it in the rain...and given all the TC calibration was probably done with that OE tyre, whether there'll be warranty issues if a rider chooses to change out to something a bit more street-friendly.
  6. Newb question (tried a search but my search-fu is weak) Why is it that the front tyre (particularly on track) is run at a higher pressure than the rear tyre? If, generally speaking: lower pressure = more traction, and higher pressure = more stability, wouldn't you want more traction on the front, given a front end slide is a harder proposition to save? Probably a bit simplistic but there you go.. I note that for street riding, manufacturers (both bike and tyre) often recommend a higher rear tyre pressure vs front regardless of whether it is one-up or pillion riding. Cheers, Justin
  7. I was talking to Dylan Code at my CSS 1&2 course about crashes and he said cold tyre cause crashes were the most common amongst the coaches... Edit: Sorry - forgot to quote the relevant posts on p1 talking about the coaches crashing...
  8. Hi rchase. I notice in the article you linked that the writer makes an observation that the DDC made the HP4 less willing to turn in - but doesn't say why. I find this sort of observation frustrating (the lack of 'why') and interesting all at the same time. Can you (or anyone) else have a stab at explaining why the DDC might impact turn-in? "...As ktk_ace mentioned you do have to adapt to the system. I have read about riders who thought the system was a bit spooky because of how well it did it's adjustments. Eventually they adapted and learned to trust the system. I can't find the original article where the rider mentioned having to adjust to it but here's a review that gives a bit of track experience with the HP4." http://www.telegraph.co.uk/motoring/motorcycle_manufacturers/bmw/9548951/BMW-HP4-review.html Just an observation here - relating to bluetooth or wireless apps for connecting to/adjusting bike systems. The engineer who works on my 1199S (and who has a brain the size of a small planet) does a lot of electronic tuning of various bike systems and always errs on the side of establishing a hardwire connection - he's noted that the wireless/BT variety can lead to all sorts of problems - canked-up numerics, etc. I guess this is a long-winded way of saying I'd probably wait a generation or so until the wireless/BT tech becomes more reliable..
  9. Thanks mate. I'll continue to work at it - I suspect it's pretty easy (when you're a simpleton like I am) to overthink things. I've reduced the number of things I'm working on to a more manageable level and not overcooking it, so the ride is gradually smoothing out. Stay safe
  10. G'day guys and girls Justin here, from Australia. Recently completed L1 & 2 of CSS (Australia) at Sydney's Eastern Creek circuit. Great experience, learned a hell of a lot. Dylan Code took our off-track classroom sessions and I thought he was excellent. Am booked for next level at Phillip Island in April, which I'm really looking forward to. Have been back on bikes for less than a year after an extended break from it (years). Still have a lot to learn. Funnily enough, after doing the schools, I now know what it feels like for sportspeople who talk about getting their techniques changed by their coaches - my riding seems to have taken a dip into clunky land whilst I try and put the various techniques into practice and bed them in. Hopefully things will smooth out over time. Anyway, probably not a new story. Looking forward to learning a bit more on here. Stay safe. Cheers
