Curious - Tyre Pressures

Does it strike anyone else that the recommended tyre pressures seem quite low at 33/36 PSI.

I think the VFR800 is 36/42 PSI, and many Honda's seem to use this 36/42 setting.

I'm not experienced with many bikes, been riding 3 years, so am curious about these pressures, especially as the Crossrunner is essentially a VFR800 but the pressures are lower.

I assume that those that have changed tyres are still using 33/36?

Just curious really  :002:

    I have always found that tyre pressures are very subjective ..... so it's down to the rider and depends on type of road and use.
    I've always found I run my tyres slightly higher than what is recommended.
    Have a play round and see what best suits your riding style etc :)

    Funnily enough when I had my first service the dealer inflated tyres to 36/42 assuming they would be the same as other tyres. Maybe its the actual stock P/Scorpion tyres which carry the lower pressure than one normally assumes.Maybe they run to higher pressure when hot? I must check my new Road Piliot 3's to see what the psi fitters inflated them to.

    I'm going to check my pressures tomorrow, to see what they set them to on PDI.

    I've checked the Michelin website and all I can find is they say to set as the handbook.

    Checked the pressures this morning, 34PSI front 40 PSI rear.  Could have lost a couple of psi over the week I've had the bike so I assume dealer set them to 36 front and 42 rear.

    Adjusted to 33 front and 36 rear and had a short ride today.  Front felt fine but rear maybe  :027: a bit squirrely  :002:.

    Will give them a better ride tomorrow and see how I feel.

    When I got mine it didnt have the handbook with it after the ride home I thought it didnt feel right so checked the pressures they were 33/36 I instantly put them up to 36/42 and phoned the dealer to complain, they said it should be 33/36 but I left them at 36/42 as the bike felt so much better  :001:

    36/42 for me guys  :007:

    Ok since I've been running at 33/36 the back end definitely feels squirmy for quite a long time but when there is a lot of heat in the tyres it feels better, but it takes a lot of miles to get there.

    Had 1st service yesterday and technician set the pressures to 36/42, and made a note on the health check.  I took her out for a good run after the service and the tyres definitely felt better.

    I e-mailed the dealer and they replied that yes handbook is correct, but they obviously don't read it  :182: but the techs don't feel the higher pressure will be a problem.  They think Honda set the pressures low as it's an adventure bike for off road use :164:
