I have 2 concerns:- 1 a) Do we (or for that matter MMC) know for sure that the new built-in stiffener will cure the problem of fatigue cracking in the early chassis's once and for all? b) By the same token do we (or MMC) know for sure that the cracking problem is not going to manifest itself in the later chassis's? Unless extensive testing and/or computer simulation has been carried out by MMC (which I doubt), I believe both the above have not been around long enough (or covered enough miles) to prove they will be OK in the long term. A cracked chassis could result in the car swerving either into a ditch or into oncoming traffic.
It's difficult to say if the solutions of MMC are safe on a long term. It's obvious that when they added the welded triangulation in 2014, they clearly know the problem of flexion and strength. Why hadn't they do the bolt on kit at that time?!!!...

I would have thought that it would have been fairly straightforward to have the camshafts driven by spur gears which was common practice in the British motorcycle industry and lasted the life of the motorcycle. It may be a bit noisyer but this would have been a small price to pay for greatly increased reliability and safety. S&S would also not have incurred the costs and time required to develop the belt with Gates.
Whilst I have had tremendous pleasure completing the 9,000+ miles so far on my car, my pleasure is now turning the into trepidation at the prospect of one of the above bringing about my premature demise. And all this from a car for which we all paid a considerable amount of money, in good fath, from a reputable manufacturer, assuming all the bugs would have been ironed out before it went to market.
There is a kit to fix up the problems encountered with the engine front pulley.
I clearly disagree with the usual attitude of MMC for 2012/2013 model owners. Why don't they tell all the dealers to offer to do all these changes when any of these poor Three Wheeler come in there workshops.
No, they prefer to keep their Policy of don't tell them anything and even deny there is any problem at all.
