Mean Time For Replacement of Key Parts

Post by Ghengiz » Fri Jan 10, 2020 6:56 am

I was wondering if there is a trend/pattern for failure/replacement of key parts such as:

1. Front tire
2. Drive/rear tire
3. Sidecar tire
4.Front brakes pads
5. Rear brake pads
6. Sidecar pads
7. Driveline coupler doughnut
8. Clutch
9. Alternator

You order for one of the main dealers, such as Heindl, you’re probably looking at a three day turnaround. Everything is easily a stock item except for possibly the alternator.

All the parts you named would be renewed when worn. This depends on what makes are installed, how they are used and under what circumstances.

As others have stated, the replacement interval depends on the severity of your usage. I will say that I keep a doughnut in the trunk. I also carry spare throttle cables and a clutch cable on trips. All of the other things on your list will visibly give you wear indication except the clutch and alternator. The alternator itself is pretty hardy. The adapter bearings have been known to have a few problems but those can be caused by too little gear lash.

Life of the clutch seems to be 40-50,000km, in my case it was the splines that wore out. Other parts will wear differently as noted. U joints are something to keep an eye on too. Rotating tires keeps the spare from aging out with never seeing the ground,

1. through 3. Depends on riding style and tire.
4. through 8. Depends on riding style and terrain.
9. Highly unlikely to be an issue.

It's like asking what's the most comfortable seat, everyone will have a different answer, and may be entirely wrong for you.

Ok, not reading the question correctly the first time, here’s my experience

Approximates:
1. Front tire - 15,000kms
2. Drive/rear tire - 7,000kms
3. Sidecar tire - forever (actually I swap the side car and pusher. When the pusher is worn again, the front is now worn so I swap all three at the same time)
4.Front brakes pads - 10,000kms
5. Rear brake pads - n/a
6. Sidecar pads - n/a
7. Driveline coupler doughnut - 30,000kms (could last longer, but swap with the clutch)
8. Clutch - around 30,000kms
9. Alternator - original

Just to prove we are all different – :D

At 20,000 km +
2016 CT

1. Front tire – still original
2. Drive/rear tire – 18,000 km (Heidenau K28, 18")
3. Sidecar tire – still original
4.Front brake pads – probably now on third set. Stock was replaced with EBC semi sintered. Then those changed out because worn unevenly.
5. Rear brake pads – again on third set I think. Friction material is thinner so wear faster. Again stock pads were changed out early for semi sintered EBC (they just work better!)
6. Sidecar pads – N/A
7. Driveline coupler doughnut – still original. Can't see any obvious signs of wear.
8. Clutch – still original. No obvious problems.
9. Alternator – is a modern car like part, so I am not anticipating this to fail ever.

Battery and starter motor etc., still original, no problems.

The pusher tire is probably a good indicator that I don't like to push it too hard.

:D

Rather than trying to predict need, I have a spare donut just in case, and a set of brake pad as they're the fastest wear item. (Semi sintered are much better than the OE organic)

Tires are easy to monitor , no need to stockpile.
The clutch should last several years/k's miles under most circumstances before one needs to worry about it.

I do suggest having a donut on hand. Not that they wear quickly or fail abruptly if you keep an eye on it's wear but not always in stock at all dealers. For tires I keep a stash bought on sale but no need to. Once you get down to the wear bars you've still got time to get them shipped to you.

There is no standard as this is a moving target as well as major variance in quality for some years.

2014 (?) to 2019 major upgrades. Mostly better but still highly variable.

Prior to that it was a total crap shoot on quality with some lasting a long time and some falling apart (which occurs even today)

There are not modern jet engines, the term MBTF does not apply.

Hey Ghengiz,

Please keep in mind you're going to get some varied advice in part because 2016 and older bikes had odometers in kilometers. Those owners may give what seems like very high mileage but they're really giving kilometer-age, possibly without realizing your bike reads in miles.

As Barry commented, you can grab a spare doughnut and just carry it if needed. While a wear item, regular checkups will usually give you a warning before things go south.

Main thing you'll notice compared to your other bikes is the rear tire, aka pusher, will wear very quickly. The stock Duro is cheap, you can mount/ balance it yourself with basic tools, but I was only getting about 3,500 miles on mine before it was time to replace. Others can quote different figures, but on my old Honda Sabre I was 18,000 miles on the rear tire, my Victory Cross Country gets 15,000 miles. Granted those tires are also much thicker/ more expensive than the cheap Duro's, but it's my fastest wear item. Last change I switched to a K28, tire was twice as expensive but if I get better life it's worth it. Brake pads are about the same as tire changes, I use my rear brake as main, don't use the front brake nearly as much (true for all bikes) and so I wear through the rear's pretty quickly. They're an easy swap with the tire, or a 15 minute job if I'm just changing pads.

The rear brake pads are easiest to just get off Amazon. They're for a one year only Can Am Spyder and not the most common for shops to stock. One of my local shops, Let It Ride, bragged that they carried every possible brake pad. They had to order them. Revzilla is my main source for tires but I also mount/ balance my own.

I would get 7,000 miles on the rear of my two wheel cycles.

Front about twice that.

Early trend on the cT is 5-8,000 miles on the rear and front almost none. But that is a different tire and dynamics are different from a 2WD as well.
