Unless it's gone too far and is reading under?

er... the lumps don't exactly come off the track ;)
(Doubt they reduce traction whatever causes them)

No, been through all 3 stages & compared with GPS, now (on rear) most accurate but still not under reading.

Sounds like it may be fine then with a 120/70 front on & fenda extenda. I just mentioned to you that it might not be as people had mentioned that with there was already rubbing with gravel etc on the standard mudgaurd, and with a FE this might be exagerated.

Hate to be negative but it makes your bike an official MOT failure and illegal! Your running a tyre which is not what the manufacturer has listed as an appropriate tyre size, would cause havoc in any accident insurance claim if spotted by the old bill's examiner.

I have to also add that I've used my ex race rear tyres on my road bike but never the front. Generally the profile on the front is so knackered after racing that it is horrible to use on the road, but I guess you may well find that out soon....!

I used a Fender Extender with a 120/70 front for 9000 miles. No problems.

What if you've a different wheel too?

Re: 120/70 Front & Fenda Extender - Potential Issue!
 

Technically yes, I know what you are getting at Chris as I have had a 70 on my SRAD (750) front end. Most police investigators are good when it comes to tyres, they just check the tread but you could get an anal one!!! Size would only be an issue if the tyre was the main contributer to the accident.

Curvy SV handles better with a 60 and with the back end jacked up an inch anyway!

Even if Suzuki recommend the 120/60, all tyre manufacturers will recommend their 120/70 (among others) for a 3.5" 17" wheel. I don't believe it's an MOT fail either, the MOT requirement is that tyres must be compatible, and legal, mustn't foul the suspension or bodywork, and the right way round, and that you mustn't mix radial and crossply. Changing tyre sizes as long as you retain compatability shouldn't be a matter for an MOT.

Some 120/70s do foul the extender if memory serves, Jimmy ran a 120/7- of some sort on his and had issues- not all tyres are the same.
