Guys,it will take MV 10 years to get the sprag right,same as the rear wheel hub.
Just sayin.
It took about 10-12 years to make it right for Triumph on their 3 cylinders range. Just sayin…

For info - the fix is in 2 parts. The sprag part itself is upgraded with finer tolerances and greater strength where required. They also identified what was damaging the previous sprags - it was todo with how the engine powered off and sometimes it put a load on the sprag causing undue wear. This part, along with a different firing up procedure (sparks after fewer turns than previously) have been changed in the latest ECU update. The ECU update takes around 5 mins to do. Whether your local dealer will charge you for it I can't say.
Bike being collected Wednesday to fit new sprag, then have to ride it to nearest dealer to get map updates, £45 for updates and tests, bargain. Cheers. Steve.

I have owned and own now 4 Triumph triples and never had a sprag issue on any of them.
What model/models are you referring to?
Triumph's have a very strong sprag clutch set-up compared to MV 3 cylinder models.
I have posted pictures showing the differences.

Hmmmm

BULLSHIT........Japanese twins up to 1,800 don't have the problem.......
MV used too small a sprag clutch.......because it was cheaper
Sort of like BS batteries, instead of the industry standard Yuasa battery
Should I bring up the POS 2nd Gen cush drives vs the bulletproof 1st Gen ones that worked on
Ducatis for ~20 years before MV existed????>:)

The 900 3 cylinders were very well known for this at the rebirth of Triumph (starting in 1991). Then came the injection models with the 955i from 1997 to 2001. At first the sprag clutch was not really accessible, and the time required for repairs made it costly. Then they change the design to make the sprag clutch easily accessible. I never really heard of issues after 2001, but within the list I was moderating (french triumph motorcycle), there was a lot of occurrences until the second 955i generation. By the way, the first generation of 955 had some other known issues (in particular because the engine was not stoping when you felt (no lean sensor): I had at that time a nice letter from Triumph explaining that my bike was not design to fall :-D but this out of topic)… Now that being said, if you compare 675 from Triumph and from MV, I'm quite sure there is difference in the design, most likely because they learnt from the past. And by the way, I had 2 955i first gen as well, and none had a sprag clutch issue, but I can tell many had issues in the list I was managing (different use of the bike, battery depleted, …)

Yes,early 900 triumph's did have a sprag problem and it was major surgery to get to the sprag but Triumph quickly addressed the problem and re-located the sprag to the side of the motor and stronger design ready for the next series of bikes.
It didn't take them 10 years to fix the issue where MV it probably will.
Also Triumph re-designed and fixed the sprag in one go.MV has had 3 attemps so far and still not succeeded.
That was my point.:smile2:

I've just bought a used 2015 Dragster before I learned of this issue concerning the sprag clutch. Now it worries me to take it for a ride. On more than two occasions while out riding, before I knew anything of this sprag clutch issue, the bike made this clanking/metal grinding noise during starting and I backed off right away and let go of the start button. It started right away on the next attempt.

I'm going to be doing the workaround from now on when starting the bike. It comforts me somewhat the it can be bump start if the start button fails. It's got less than 2400 miles, bought it from a private seller so no warranty if the sprag clutch needs replacing.

Is replacing the battery to a lithium recommended at this point or should I just wait till the sprag clutch fails then just replace both then? Is it useless to update the ecu now or just wait until the sprag clutch is replaced?




Theoretically yes, as long as you can get the engine to spin to higher than 1000rpm the ignition will start firing.

Try the workaround - press the starter button in, pull the clutch lever in untill the microswitch just engages and engine starts spinning (keep clutch in that position as if you are riding the clutch on pull away) - engine should start up easier. Not fully disengaging the clutch from the drive train helps to place sideways pressure on the drivetrain / sprag clutch making it 'grip' more. (my theory here - could be some other engineering reason for this but this does work)

Before my warranty replacement i lived like this for quite a few months with no starting problems using the workaround.

Just had my Rivale collected as it would not start, they have inspected it and low and behold it is the Sprag that’s gone. Apparently there are delivery issues and it will take 3 weeks to get one in, so no bike until the end of June grrrr. Good news is the warranty that came with the bike are picking up all the costs. Well at least they can fit my new tail tidy while it’s gathering dust in their workshop

2017 b3

Yep my 2017 B3 sprag is clacking hard. Headed to dealership next week. The bike is 3 weeks out of warranty but it looks like it's covered.

Correction: Just got my quote back yesterday from the dealership here in Chandler AZ that my 2017 B3 sprag is out of warranty and therefore NOT covered. I'm contesting it. I emailed the dealership 1 month before warranty expired that I was concerned it was going out and made an appt. to get it in right away. However I had to reschedule due to a surgery. I'm going to be a bit heated if they don't cover it. I copied the original email and resent it to them this morning, I will be curious to see what they say. This dealership has been outstanding, I"m pretty sure they will step up.

I have finally lost faith with MV the lack of service agents in New Zealand and no definate answers to sprag clutch starting issues.
My brand new 2014 Dragster I purchased with hard earned money has been an on going disgrace.
3 sprag cluch replacements and 3 different recommended batteries in under 19000 kms.
I had to pay for the last sprag clutch and NO guarantee that version 3 is any different to version 1 and two.
I originally emailed Australia and The big cheese in Italy after sprag clutch 2 but no reply!
Many kms of travel* to get servicing, and too many clacks and non starts mean I have finally relented, lost many dollars faith in the brand and decided to buy another known reliable brand.
The cheek of MV NZ to not even explain to techs or press how version 3 spag clutch is different to version 2 AND offer NO warranty when fitted.

To "esq'z me"
*AgustaDragster 09:22 PM Today 13 oct 2019
Motorad Wellington are no longer MV service agents and have not been for a long time now.
Robbie and Vicki I am sure were as described.
You are aware of the following link? https://mvagustanz.co.nz/dealers/
Red Barron Lower Hutt Was briefly an MV agent as well.And what happened to Red Barron Auckland who used to be an MV agent.?
Its The importers who should be responsible and with a lack of dedicated service agents will be severely constrained when offering a premium priced product.
Preety much explains everything.

*Esq'z me
And failing to maintain the battery?
With the MV battery charger that was with the motorcycle all instructions were follwed.
Plus Motorad Wellington at one of the Sprag clutch replacements also had me pay for a new battery at their request with very little kms on the bike.
I am amused that you are suggesting ALL MV owners with sprag clutch issues (and there are many on the forums) have "brought it all on themselves."

@AgustaDragster ... wow, after 5 years of no posts you have suddenly become very active. And all to slag on MV because about your disappointment. Where have you been all these years?

Shame your dealer is gone. It's happened on almost every market. The dealer I bought my 910R from 11 years ago disappeared the very next year. 2 others have come and gone in my area since then.

Regardless of dealership solvency and longevity, The sprag problems were addressed by MV, although some dealers never really went to bat for their customers along the way. Wondering if you ever got the ECU mapping updates that were a part of the sprag failure remedy?

As for the battery....it is a well known fact that the original Chinese battery supplied with your bike is a poor quality item, and that the battery is a prime cause of sprag clutch problems. Buying a better quality battery .... AND keeping it on a proper battery tender when the bike is not being ridden... are key elements in preventing sprag problems.

Again, I am sorry for you that your 5 years of ownership have proven so disappointing. I suggest you buy a Honda. They never have any problems and their dealer network will be with us forever.
