dave moss on youtube suspension guru recommends 34 up to 38 tyre pressures what are you guys running im not getting on with my bike its a hard bastard to ride fast runs wide back end trying to kick me out of seat mite book in for set up
What tyres ? SP V3, owners manual says 26 R/33 F, cold; SC V3, Pirelli pressure chart says 23-26 R, 29-32 F cold/25-28 R, 30-35 F hot. Slicks about the same, maybe at the lower end of the SC V3 spread. IMO and it is only my opinion, 34/38 (which I assume is measured hot) is too high. Andy
andy ive gotpirelli rosso 3 on the now had them on the bmw s1000rr 2015 no problems bike is running wide cant hold a line feels so stiff
I went out in mine today and it does feel stiff, once you get used to it though it’s great through the corners, I’m running 32F and 29R, I’ve found you notice if the rear is too hard really easily.
Silly question, the Pirelli Rosso 3 doesn’t come in a 200/60 profile so you have recalibrated the electronics for the different tyre size ? Andy
Hi. I have been playing with pressures too after seeing somewhere Dave Moss states 34 - 38. I am not a subscriber to his channel so I can only think this must be hot. I just checked Pirelli site for their recommendations on the standard fit tyre (Diablo Supercorsa SP 120/70-ZR 17 front & 200/60-ZR17 rear) and could not see a recommended pressure listed. I pinged them an email and within 10 minutes had the following response which seems to fit the manual and common sense (big up to Pirelli for the swift reply):- Dear Richard, Thank you for your recent email. We would recommend the following track day cold pressures for your bike and model respectively; Front-31 Psi Rear-28 Psi Thanks Mannie Contact Centre Pirelli Metzeler Moto UK
Hi Tony, no, but Andy's post #2 above refers to the manual (track settings). The manual road settings for solo riding are 33.36 F and 30.46 R. I have been running at 33 F and 30 R and it feels good. I would not go any higher for spirited road riding unless two up (but my rear seat is in the garage loft and will stay there!). I think that 29 R would most certainly be worth trying per Ibb1's post. Hope this helps. Richard
Working with cold tyre pressures is a really bad idea and you should definitely not do it on track where there is a huge difference between fast and slow riders and different tracks. The front is not a bad recommendation since it will go up to around 34 psi once hot but we all run the front at 35 - 38 psi HOT on track since the Pirelli and Metzellers are very soft and you need the pressure to give you stability. 28 psi rear cold is very likely to shoot up to 32-35 psi once you get it hot on track depending on your pace which will destroy the tyre. Even a slow rider on a V4 is likely to get a big jump since the bike has so much power. Everyone runs around 25-26psi HOT and racers often a bit lower.
If you set your suspension sag correctly front and rear it will make the world of difference to turn in and the ability to hold a line. Dave Moss has set up a fair few V4s now and the consensus is that the front is (too) soft and the rear (too) hard as delivered. I beefed up the front pre load significantly and reduced the rear significantly following his advice. After some fine tuning of compression and rebound damping I have fast turn in and improved steering.
Be wary of how far you go with preload since you are reducing spring travel, if you have to really wind it up then you are much better to change to a harder spring instead.
