Clutch cable

Read recently that these can snap prematurely, so I got one delivered. My question is, do I replace it now, or carry it to fit when it decides it's had enough?
I guess I'm asking can it be fitted by the roadside?
I do realise that it will be during a mini hurricane at the time too 

Yep it can be done if you use insulation tape to tape old cable  to pull new one through its old route...then its just couple spanners to adjust it... it more than go at lever keep an eye at lever see if wire is fraying

Yes, for the ultimate protection against clutch cable failure, fix the new one to the old one. Assuming you have the 'standard' toolkit that (once) came with the bike you can fix it at the road side.

Personally (being a tight-wad!) I wouldn't take off the old clutch cable until it snaps - I'd just make sure that I had new cable with me so it didn't matter. It won't stop it happening at the most inopportune time - that's impossible!

Being tight-wad is why we have cb's cheap-great mpg-value for money-long lasting

Cheers guys, thanks for your help
