Tyres that age are not recommended, the rubber hardens and loses it's grip and I know from experience. I bought my 1980 400na last year, 1,400 gen miles with lightly worn original Bridgestone Mag Mopus tyres. Riding back leaning at a roundabout on a bone dry road, the back end suddenly slipped away, nearly lost it, slightly shaken but didn't have an off. I did some research on the subject and replaced the tyres. Never had a slip since. The offending 34 year old Bridgestones  |

I mentioned a while back when I first got my SD they were fitted with a set of Metzelers which looked like a low mileage set. When I queried their age with Metzeler they told me that age was not a factor in replacing them. I found this strange as every other manufacturer seem to recommend replacing anything between six and ten years old. I did some more research and found that my front one was made in 1990 and the rear in 1992..!!. Needless to say they were replaced by a set of Dunlop Arrowmax ASAP.

In my opinion it's not worth risking life and limb on old tyres, not to mention wrecking the bike you may have just restored and probably spent a few thousand on.  OK, if you are building a show bike and not a rider and want the original tyres fair enough, but on a rider a definate no no . |
