Faults on higher mileage bikes

[Gills]

Despite the CB generally being very reliable, I thought it would be useful to have a thread for people to post non-service parts which have failed or needed replacing. There seem to be a few things which have caused problems (water pumps and wheel bearings come to mind) and it would be interesting to know how frequent they have been and at what mileages.

I've had a couple of issues now:

• Front wheel bearings - 25k miles
• Dog bone bearing disintegrated - 37k miles

• steering head bearings, 6k km

steering head bearings, 6k km

That's not high mileage.

If everyone posts every fault they've had then it defeats the point of the topic.

Very true! Mine's a 2013 model.

What do you consider to be the cutoff to call it high mileage?  I know some riders who would think 6K on a 5 year old bike is high mileage.
 

I had the water pump seal fail at 9600 miles.

2014X non ABS.

Headset bearings started to get notchy and rough around 6000 miles.

Water pump complete trash by 12,000 miles.

Valves went tight by 7500 miles and an almost non-runner by 9000 miles.

The rear shock went by 10,000 miles. It had no dampening ability left with me at 230lbs in gear and 60lbs of luggage.

My bike is a 2014 model. I've been riding it since January 2016, at which point it had done about 5,000km (3,000 miles) so I think that any unusual jobs have fallen to me.

Thankfully, I've had a pretty good run.

My rear wheel bearings went at about 60,000km (37,000 miles). At some point after, and before 107,000km, my fork seals needed to be replaced. I can't be more precise as my servicing spreadsheet became corrupted.

Other than that it's just been the usual - tyres, chains, sprockets, a couple of headlight globes, filters and brake pads.  I replace the oil with a semi-synthetic, on-schedule, and I have the valve clearances checked per the book, too (I've had a couple out of spec on occasion, but not so much as to be a concern).

It is using a little oil now, and I typically top it up mid-service cycle which sees me fill about half the sight-glass. However, performance seems fine and this oil loss is not significant.

The bike is now at 150,000km. It is ridden daily over longer distances, so the engine runs at temp.

I need to add, I replaced the OE chain at 11,000 miles with a quality DID O-ring chain.

Also replaced the battery at 12,500 miles but that was expected. The bike was four years old.

Scorpions replaced at 6000 miles with 705's in 150/70R and 120/70F.
