It's just a slightly more mechanically sympathetic way of achieving (virtually) the same gearing.
In theory, the smaller front sprocket gives the chain a harder time as it has to make a tighter turn to negotiate the sprocket. Also, the smaller front sprocket reduces clearance on the upper chain run so the chain can rub on the nylon swingarm guard and wear it away over time. The advantage of choosing the small front sprocket is that it's quick and cheap. On the other hand, retaining the standard 15 tooth sprocket and fitting a larger rear will give the chain an easier life and avoid any rubbing on the top run. The downside is that it requires a longer chain (106 links). My 14/39 set up is working fine for me at the moment and I won't be changing just for the sake of it but, if and when the chain and/or sprockets wear out, I will replace them with a 15/42 arrangement. |

What sort of life are you getting out of a chain and sprocket set?

By the time mines get replaced (full renthal set currently) they’ll be on about 18k. Atm they’re on 16k and the rear teeth are getting a wee bit pointy and sharp front isn’t to bad with only the slightest hint of hooking.
I’m a bit of a Lehman when it comes to chain wear but no matter the sprockets need done so chain will get done too |
