120/70/will it fit

[sottondan]

just wondered would a 120/70 fit a curvy sv650s? nice n simple question. Thanks in advance

[Dangerous Dave]

Yes it will, not worth doing to be honest and many people drop the forks through the yokes and this would compensate for that if it has been done. Plus the SV650 is not approved to run with a 120/70 tyre so if you have an accident you are buggered!!!

well i just got offered a set of used (still loads of rubber left) d207 gp tyres rear is same size but front is 70 profile but they are £30 and im skint as long as they will fit i will have them would it be an idea to drop forks 10mm to compensate then?

[Dangerous Dave]

If you do it take it for a ride as standard first if it feels good then don't mess with it, tyres won't last long anyway so why alter the whole bike to suit.

Tip for anyone considering dropping the forks by 10mm is to fit stiffer spring in first, the OEMs won't cope!!!

could i be a cheapskate and stick a spacer on top of spring ;):)

Yes it fits and it works, with standard mudguard and a sticky tyre you get lots of noise with gravel getting spat out.


My SV isn't approved to run GSXR suspension either... the insurance are aware that it's got "GSXR front running gear" so that includes a 120/70 ZR17 tyre.... Should be alright I reckon.

[sottondan]

sticky is what i want lol are they any good then?

[yorkie_chris]

Not really. Maybe a little different to turn in but nothing massive.

[Steve_God]

Yes it fits.

If you have fitted a Fenda Extenda then you may have to readjust the mudguard position slightly so that it gives more clearance, but after that there's no problems with it.

It will work fine without going to the effort of adjusting the forks - I personally have noticed bugger all handling differences by doing a straight swap, other than the initial 'tip in' seems faster.

Nah, that just increases preload not stiffness, gives you more problems to go on top of your soft springs. But DD's oversimplifying I think, the standard springs will still be fine for lightweights.

[sottondan]

i need stiffer springs im 14 1/2 stone lol and when my missus is on back she aint light her t**s are huge lol

[northwind]

Hah, in that case you need 'em anyway whether you drop the front or not :D

[sottondan]

yep progressive springs and some 15weight oil coming up me thinks

207s are good tyres, but a little old now ...

The 70 section front will make the handling odd, but it is physically 'safe' to fit a 70 section, yes 8)

p.s. Any pics of you GF!!?!?! :smt045 :D

Only if you told them it is running with a differnet size tyre Chris, and technically still not legal if you have a prang as the accident inspectors have a little book of everything regarding what type approval a vehicle has.

I've only ever ridden the SV with a 70 profile front, and it rides great.
