Most motorcycle problems are caused by the nut that connects the handlebars to the saddle.

TYRES

Post by freeride on Thu 12 Apr 2012, 8:44 pm

I'm sure we have been here before but:-
I pumped my tyres up to 32F/42R as advised on the forum the other week as it was on about 25F/29R.

Usually I'm a fair weather rider no rain and warm. However, I went yesterday at 5.30 pm and that was probably the coldest I'd ever ventured out on this steed. Bike was a bit different to the usual.
Parked up at 6.00pm and came home at gone 07.30pm when it was 5 degrees or so. Even after 15 mins ride the tyres felt like they were all over the place and followed every line in the road. I stopped to see if there was anything wrong twice and all looked fine.
Before you ask the rear is squared off a little but it is difficult to tell unless you have a new tyre next to it. I'd say the centre was 50% worn more than the sides.
Answers please the easy one is let the tyres down and only go out in the warm.The bike was so different......

A quick point:

What tyres have you got? The higher pressures are only definatly suitable for Bridgestone BT-45s. If you have other tyres you should probably try the 'standard' pressures first (29F/33-36R)

Sorry to hear the pressure didn't help on this one.

Some other ideas:

How's the rear wheel alignment?

Are the steering head bearings stiff/"notched" or too tight?

Thanks.

As it was fine before I put the air in I'll let some out and check the alignment. Maybe the pumped up tyres don't mix with the suspension setting.

Have to admit my error I checked the tyres again today and I had wait for it 48 in the front tyre. I clearly didn't check it properly last time and I'm sure this will account for the very very poor ride I had last time. When and if it stops raining I'll try it.

Thanks
