Hello Nigel
Chester and Illiad Blue, I'm on Rydtalog Moors above Mold. Thanks for your comment 2.1 bar rear and 2 bar front thats what the book says also I think. Thats just over 30 psi rear and 29 psi front which seems very low, for a 1400kg machine. Interestingly On my Moto Guzzi, yes got a number of bikes the book pressures were 32 front 36 rear and yet Michelin pressures for their Pilot Powers were 36 front 42 rears, and that transformed the handling. Bikes are different obviously, the proof in the pud will be how they wear, if too high then the centres will wear, and the last set didn't, although it was in the last three or so thou that I upped the pressures, improved the way it handles, so stuck with it for the new rears. Probably got 500 or so in fronts then will fit the Conti's and stick 36 in them. I like to experiment, track days on the bikes etc, tyre compounds/structure advancing, side wall stiffness lower rolling resistance etc. The V's are 10yrs old now, is the book still correct? I'll let you know how I get on splashing around Snowdonia! One final thought I bet a 997 Carrera doesn't run 30psi in its rear tyres.
I've only seen one other 255 in the area, that was black responsibly crobbing through Heswall highstreet in the summer, yep I was bimbling on the RSV behind, they are lovely looking things from the rear eh! Taxi now go and pick my missus up from hen night!
All the best
Mark
