Hello everyone ! Im in the dilemma whether to replace just the chain to gain 5-10.000km more before I replace the whole set, or replace the whole set already from now.. Someone who has seen many worn sprockets maybe could help ?.. Thank you in advance !
It's a false economy to change just the sprockets or the chain as one will wear the the other out to the same condition in no time. Changing both will will give a longer life to both parts.
Always replace them as a set. But if your skint, then I guess your choice is limited. Worn sprockets wear new chains faster. The front has shark finned and is worn, the rear too is worn but to a lesser extent. I'd replace all as your there doing the chain anyways. As Carr says, its a false economy.
Many years ago when I was young and foolish, I replaced the front sprocket on a bike because it was worn to the point of jumping chain links. I thought in my 'wisdom' that the chain etc. was fine. A few weeks later the new sprocket was as worn as the old one due to the worn chain knackering it, and this was on a lowly 250cc bike. When I first got my Monster on the road I was using Renthal alloy rear sprockets but it munched through them like they were made of Parmesan so I bought a Supersprox rear in the hope it would last but left the front sprocket and chain as they looked OK (have I learnt nothing?), a year and maybe 3-4,000 miles later the Supersprox looked like a circular saw blade, so last year I swapped the lot again and hopefully it'll last better this time (so far so good). Do yourself a favour and change the lot, or leave it as is until you do...
Ok this sounds clear as an advice.. Are steel rear sprockets more durable than the alloy ? Are there any other disadvantages for choosing steel ? Thanks again !
Personally I would use steel. In my experience wear rate on steel chain and steel sprockets is comparable. Steel chain on alloy sprockets IMO means more sprocket changes, but that to me means using a lesser used chain on new sprockets. If lockwiring the rear sprocket; drill across the corner of the nuts, not the studs - firstly nuts are cheaper than studs; secondly lockwiring the studs doesn't stop the nut from coming undone an amount before it works......it depends on how close the stud can be drilled to the tightened nut - and that always means use the same nut on the same stud each time.......until the sprocket is changed for a slightly different thickness.

Weight. And look. I replaced my chain at 4k, sprockets weren't changed, because it was a cosmetic rather than wear change. Otherwise I'd do the set.
Not sure the stud is even drilled Al, look closer, it's just wired round it, then off to the next stud? If this is so, it's not of any use as far as I can see.
