Taller Profile Tyres....120/70 - SV650.org

15-08-06, 01:31 PM

Recently got the bike sorted out at Steve Jordans' (Top Stuff, I must add

). Anyway (in the three hours that was spent sorting out my knackered bike) a new tyre was put on, although Steve suggested and put on a taller profile tyre i.e 120/70 rather than the 120/60. All I can say is that it feels great, another worthwile mod for the SV's front end.

Anyone else done this?? Opinions?

Cheers,

B

dont you mean a taller tyre? 120/70 opposed to the normal 120/60.

Okay, why? I'm seriously thinking of putting on a 120/70 for my next front, so am interested in what you feel is good, bad, and a descriptive general opinion.

Well... It raises the front, which in turn changes the bike's geometry and slows the steering. But it does change the contact patch on the tyre, all other things being equal a 120/70 will put more rubber on the road when leaned than a 120/60. All other things never are equal, mind

You can get a steeper profile on the new tyre- if you switched to a "pointy" tyre from a "flat" tyre, it'd possibly turn in faster to compensate. But most people lower the front to compensate.

It just feels like you are more planted to the road, gives you a bit more feel and when hitting a corner and lean it over it stills feels planted.

Not technical stuff mentioned above just that it feels safer! Haven't noticed that the bike is any slower into corners etc.

The only thing I would say is new rubber replacing old almost always feels miles better you'd really need the 2 fresh tyres back to back to do a fair comparison. That said the boots on the Kwak are up for replacement and as it takes a 65 profile front, I've been running a 60 for 11,000 miles, was thinking of going to a 70 so will watch this thread

Hmm, I wasn't sure a 70 would fit with the extenda fenda. If someone has this combo, let everyone know.

Cheers Bobit69, the original 60 profile front tyre really is a case of trend over function...
