Default SV650 Tyre Pressure

Haven't done it for a couple of week so did it this morning, but my mind went totally blank.

Is it 33 psi front and 36 psi rear? It used to be on the chain guard but now I have a hugger there's no reminders.

Also is there anywhere that has a pump for bikes which doesn't involved losing knuckle skin on the brake discs?

Last thing; what difference does under inflation/over inflation make to the bike, I know this is a bit basic, but I don't really know.

Under will increase the amount of rubber on the road, in winter not such a bad thing, but will also increase wear. Over will reduce the contact patch and thus decrease the grip, never a good thing.

Knuckles. Use a foot pump.

Or don't use a pump at all....everytime you go to the petrol station, stalk the air compressor, so that when another motorist is finished, you score some free air.

It's free anyway - well except for the cost in fresh skin every fortnight.

Ah, but underinflated tyres can have problems with water dispersal as the tread can close up a little as the tyre flattens. It does help to get heat in, mind.

I run my Roadtecs and Stradas higher than recommended, 36/39, they're stiffer at the higher pressures and feel a lot more stable. It doesn't seem to lose me any grip which I'm actually using.

I have to pay around here....damn this affluent neighbourhood.

I find the trick is to park side on(LHS near the compressor) and then feed the nozzle from the left to right, between the brake disc.
