Hi,

After a recent incident with my chain (see the last paragraph for info). I'm thinking of replacing with a 525 chain and sprocket set. Does anyone know whether the wider set up will mean I need to get a new swingarm rubber guard?

Thanks J

* My 520 chain in good condition, well lubed, with plenty of stretch left, no rust etc. let go while I was doing c.75mph and wrapped itslef round the rear axle putting me into a 200m lockup across 2 lanes of motorway. Luckily I kept it upright and the car on my inside saw what was happening...but still, I'm very keen not to repeat this experience!
