Larger Section Front Tyre...

[Super T.I.B]

I remember Matty saying that he has fitted a larger section front tyre to his Monster (from a 60 to 70) and was wondering what are the benefits and what are the downsides to having a larger section tyre fitted?

Mine is just about rooted, the right side of the tyre is worn right down while the left side is still fine  DAMN ROUNDABOUTS!

When I had it fitted Ron & Rob told me that the plus is that you will get a more positive roll into and out of corners.
The downside being that it will be slower to steer.
So far though I haven't really felt it was that much slower on the steering side.
But the better feel in cornering is great for me.

Super - just do some rouad-abouts in the opposite direction, turn right instead of left - that will fix the wear problem! 

[mattyvas]

Spider I think your a little confused with the way we use round-abouts here.
Unless you use-em different south of the boarder.

aren't they like coins or maybe football teams? You just pick a side and go ? 

[mattyvas]

yep pick a side, pick a gear and nail it.

+1. Just do it super - give the 70's a try.

btw, I can't remember where I read it, but the uneven wear is pretty normal.

[mattyvas]

It's also road camber that helps.

[Spider]

cool, my front is gone to and I think it's the left hand side that is worn....and I know it isn't cornering skill that is the reason.

I also took Matty V's advice and ordered the 70.

Ah, this is good to know.

I want to pump up my seat height to max on the rear,.. which apparently makes the bike turn in faster. So I can just use a 190 on the rear, 70 on the front, & we'll be good to go.

Two sweet cosmetic changes for next to nothing.

The other big plus is the noticeably reduced number of reports of dented from rims from people using 70 profile tires. (I've got a ding in mine which I got while running a 60...)

The "taller" sidewall makes the the tyre more flexible over bumps and takes a bit of pressure off the contact patch. Compared to the "60" it might feel not quite as planted, particularly on quick turn in.

My FZR1000 came standard with a 60 series front and when they became unavailable I went to the 120/70 and it felt really vague when peeling into a corner and didnt inspire confidence. The suspension had to be reset to get the best out of that profile tyre.

I s'pose this is all irrelevant if you spend most of the time with your front wheel in the air?

I ride a 620. That just does not happen. 

[CairnsDuc]

Is the only difference with the 60 vs the 70 is the sidewall height?

Sorry my knowledge on the black rubber things is limited, but I like the Idea of the protecting the rims a lot more, The amount of potholes on the Goat tracks they call roads up here is insane in the wet season.
Is there any other issues such as clearance of mudguards to consider when switching to a 70 series?

[loony888]

the 60 is supposed to have 60% of the tread width in height and the 70 has 70% of the tread width in sidewall height. doesn't really look like it does it? they definitely ride different and i think the profile of the tread on the rim is rounder on a 60.
i dunno about roy nexus6' idea of the 190, jacking up the rear to make it steer quicker then putting a 190 on will not only slow the tip in and change of direction down markedly, it will probably make it feel like it wants to tuck on tighter corners. i'd definitely stick with std sizes, but that's just my .02c
