The companies that make the most thorough use of statistical control during the mfg process, seem to be the manufacturers who have the most consistently reliable products for sale.... I think there is a reasonable correlation between the two.
I was a bit disappointed that companies in the lower tiers of mfg were not included in the write up.... Kymco, Hyuosong, the Indian mfgs, etc. One could presume they would have fared worse than the 'less reliable' companies as reported here. Confederate, etc.... the 'boutique' mfgs were left out entirely. Not surprising, if the production run is measured in less than 100 units a year; but it would have made a stronger case one way or the other.
Most of the recent start ups -- the reborn Norton, Royal Enfield, A couple of others whose names escape me at the moment, have died off due to lack of market penetration, and the ability to sustain themselves through the first 5-10 years. Victory is a prime example of NEARLY making it through the painful years..... so close. Polaris is still at it in the bike market, just moving name plates to Indian.
The problem for Polaris, is almost all of their product lines have not been street vehicles. Warranty work on ski mobiles, and watercraft are not reported with the same level of visibility as things the DOT has a hand in. they don't have a long history selling into the DOT environment. With the 3 wheelers they are now marketing, they will learn the rest of it, I think. (I believe they are the overall corporation for both the CanAm Spyder, and the Slingshot?)
I was surprised that KTM didn't make the list over Polaris. My experience with them is one of bulletproof, nigh on Japanese levels of reliability. There are a few smaller-named makes here in Europe, but the reliability factor can vary. Husqvarna makes pretty solid rides, but fellow Swedish manufacturer Husaberg appears to make bikes that are seem more at home in the workshop.
Royal Enfield has been going for decades. They have decidedly lower-end build quality, but their archaic and agricultural design means that you can stick a roll of gaffa tape and an adjustable wrench under the seat and fix pretty much anything in minutes.
Triumph was really revived when Bloor took over the works in the mid 80's. They've had a few shonky items here and there, but over the last couple of years, they've been pretty solid.
As far as Honda, I'd trust them to last a lifetime in either two or four wheel variety. Gear-driven cams may add a tiny bit to the weight, but it means you'll NEVER have a problem with cam chains or the timing of the cams at high revs again. I've seen a VFR750 with a genuine 200K+ odometer, and you'd never know it had done more than 20.
I'd have a genuine interest in seeing Toyota make a motorcycle.
