Have accepted that original shocks are poor so am experimenting with different springs on Hagon 2810 rear shocks but not got a satisfactory ride yet - could the Pirelli Sport Demon tyres be responsible for a hard ride?
Ride feels like tyres over inflated but 36 psi front and rear as handbook.

Thanks for the reply.
I have always had lower pressure in front than rear tyre on other bikes ,but why do Moto Guzzi and Pirelli both specify 36psi front and rear for the V7?

Put this way, Leofric has a problem with a hard ride and I don't. The difference is?

Don't let tyre pressures down it sounds more like your suspension springs are at its limits . Bigger bike springs to mind . I'm the opposite I'm a wimp and struggle to get suspension working lol

Remember, forgetting how much they cost but these are bottom of the range, not sports bikes and as such come with basic suspension. I'm 14 stone and don't have a problem but I have changed the rear units to Ikons and put Hagon progressive springs up front, mainly for comfort but it also corners a treat. 33 front and 36 rear works for me but if you are bottoming out the suspension you could try upping the rear to 40 psi and using a heavier than standard fork oil. This will either work or your spine will shoot out the top of your head at the first pothole. Good luck with that!

Have you asked Hagon for their recommendation? They set up a pair of shocks for my Laverda GTL a few years ago after I told them the combined weight of self, the good lady and luggage.

yes - Hagon are fitting 26kg (I think they said) springs to my 2810 shocks. Nothing seems too much trouble for Hagon - they are very helpful. They then recommend trying shocks with these new springs at minimum preload and number 4 or 5 setting on damping. Not received shocks back yet - will see how it goes.

sounds like the spine shooting out the top of my head might make the tinnitus worse! think I will avoid 40 psi in rear tyre.

Might be a rather drastic and permanent cure for the tinitus; seems that every one I know in my age group has it.

To be serious, tyre pressures are all part of the suspension system and a bit of experimentation using the manufacturer's recommendations as a guide line won't hurt. I was surpised to find how much harder the ride felt after changing to cast wheels from spoked, but that may have been down to them being 3.5kg lighter and less of a rebound load on the suspension. I've had a lot of different sized bikes from various manufacturers over the years and all came up with the ratio of pressures I suggested. The MG handbook is the only one I've seen that's different, but then what do I know, this is my first Guzzi!

I'm fairly light - 11 stone - and I run my V7C with 28 front & 32 rear (AM26 Roadriders). I only ride solo with no luggage. The bike handles beautifully, a little hard at the back but not so it's a problem.
I used the same pressures on my W650, I'm pretty sure they were the recommended pressures. 

The recommended pressures on my Enfield (500 Bullet UCE) are 18 front & 28 rear! Sounds bonkers but, again, it handles beautifully (AM26's again + Hagons). Tried it once with 28/32 but it was all over the place.

I really like the Roadriders for grip in extremis, but they wear fast. I found Bridgestone BT45's to be just as sticky but last a little longer for not much extra cost. I'll be trying them on the Guzzi next time.


it's about the ride
