Freaky handling

[mossy1200]

You guys run them high.

I run 32 front and 34 rear even when 2 up.
I like to judge mine by the colour they run at.
Blue is low pressure and overheating and grey is to much pressure and running to cold.

Tip in speed is most likely shape in the tire and rolling off a worn out centre line.

That's under inflated for most tyres on big bikes for road use. The manufacturers know a thing or two about their own product & tyre construction has moved on from the 80s.

They get hot enough and stick to the road ok.
Maybe touring tyres would last better with 40 odd but I run sports tyres and 5tho out of rear is fine for me and then a new set goes on.

36 f 42 rear here
has been for most of my bikes

A tiny bit of squaring can feel like a vertiginous precipice because you have to mount the lip and then drop off of it. I think the square tyre is most likely.

[QUOTE=baffa;1130413279]Hey guys,

The bike has felt like it is more willing to tip into corners recently, which was odd, and I thought it was just me, but I went for a ride yesterday and it had a really freaky handling trait. Basically the rear wheel feels like its rolling around, or stepping out when you lean over.

I rode my cosins suzuki 450 twin i had one at the time and omg seriously i think was going crash it

after going few feet he rode it at speed i guess was used to it the front tire was like trianglated

Badly worn so felt like it wantede to veer suddely i think was scarest thing ever ridden hehe

[_Shrek_]

have you checked that the tripple clamps are tight?

are all the bolts in also?

this would cause the bike to drop in the corners as well

Triumph Street Triple rec 34 front and 42 rear

Speed Triple too.

Check yer rear axle, same descripton happened to someone on the race track recently and they couldn't figure it out until they decided to pull it apart.

Some Contis recommend real high pressures. Aside from tyres which would be my first call, would be steering head, but other bearings could be suspect. Get a mate to help hold the bike & check the steering with front off ground & check for any stiffness or notch in the centre, & wobble the wheels checking for play.

Yeah .. Conti recommended 42psi on the rear of my 650 (Road Attacks) the 1250 Bandit recommends 42 psi rear - 38 on the front standard. 4-5 pounds under that recommendation and the bike feels odd ...

Yup ... put new tyrs on the 650 about three weeks ago -the rear was shot (bald asnd square) and the front was OK but getting there (Triangulated) so I changed both - I could not believe how much difference they made ... I had got used to the old tyres over the 5,000klicks I'd had the rear ...

That seems a bit to me (not arguing) I run 38r/34f on my ZX6 and it feels excellent, if the rear drops below 35ish it'll slide around a lot and lose traction in the wet

That's in your head man. The biggest loss of traction in the wet, without standing water (puddles), comes form the tyre temperature dropping and becoming less pliable. So it doesn't conform to the road surface as well. Softer tyre means more deflection/heat.

In standing water it's the tread doing it's thing. But, any tyre would need to be below 25psi before tread groves started getting closed up by tyre distortion, and then start sliding.
