Strange, usually you have to do the whole lot.

That’s just what they convince you so you spend more money.

But if the sprocket is worn and will be going soon it’s often sensible to just do it then while the chain is off.

Then again a crafty person can change the sprockets without unlinking the chain. :)
 
As I said, sprockets were checked and found to have very little if any wear. Chain wasn't kinked or stiff, was just stretching for some reason.

At the mileage it’s expected.

The moment they start stretching they don’t stop and rather safe than stuck next to the road.

Or worse, having it smash engine to pieces or get stuck in your rear wheel.

BMW F850?GS teaser

Yep.

Leading up to the EICMA (Esposizione Internazionale Ciclo Motociclo e Accessori) show in Milan, Italy, opening doors to the public in a couple of days, BMW Motorrad has taken the wraps off two totally new middleweight GS models. The BMW F850GS and F750GS feature brand new 853cc inline two-cylinder engines producing 95hp and 77hp respectively. They include two counterbalance shafts to reduce vibrations and a new 90-degree journal offset for a more exciting 270/450 degree firing interval. This powers the rear wheel through an anti-hop clutch, six-speed transmission and chain drive (positioned low on the left side of the bike).

I wonder why BMW decided to put the chain on the left side of the bike (F850 & F850) this time around?

Probably the same reason as why the 1200 had its final drive moved (according to the marketing material anyway) - it means the exhaust can go to the right side meaning that if you need to push the bike you don't have to worry about 3rd degree burns

Actually the chain and sprockets wear together, and replacing one without the other makes the parts wear out faster. So your new chain wont last nearly as long with old worn sprockets.

Most likely no the first chain on the bike.

Unless the sprockets aren't worn.

So guys, anyone know if it's worth taking the bike to Randburg Motorcycles for a service and new chain? Reviews seem to be mixed...

Honda Weltevredenpark if it's not too far out of your way.

Yes that’s if the old sprockets are worn.

If they aren’t, no need to replace them.

It’s not a superbike and even then all depends how you ride.

Sold my Triumph at 36000km with original sprockets and chain still in perfect order.

Interesting, didn’t know that.

I just assumed it had to do with the liquid cooling but needing more space.
 
I only made it to 30'000km with my chain... it had gone from 50% to over the limit in 2 months of neglect.

All 3 sales people at Trac-mac gave the "wasting my money on a chain only" line.

The way I see it, even if the new chain lasts only 20'000km... it's still cheaper and less hassle
 
So bike will be done today, amazingly received a call from Honda earlier
/shocked

they are doing a road test to make sure everything is kosher, payment of insurance already organised..... question is just when the money will clear, because I won't be able to take delivery before that
/frustrated


don't worry guys, i'm almost done complaining ;)

Unless the sprockets are seriously warn to the point where the two sides aren’t even uniform any more there really is no justification.

If it’s obviously worn and ignored that’s a different story.

Interesting that I’ve only ever seen this notion of wanting to replace everything at once from third party shops that make their bread and butter off it.

Dealerships don’t do it and also aren’t super excited to change a chain “just because”.
