I learned a couple of things at the NoCal rally this week. I spoke to the BRP rep about the Kenda rear tire wear issue and the problem of getting a dealer to put an non-Kenda tire on it. I'll summarize his comments;
- BRP has no policy or contract language with dealers that would prevent a dealer from installing a non-Kenda tire on a Spyder. Any dealers who say so are mistaken or are using that as an excuse for their own reluctance to deal with the problem (incidentally, my dealer said 'no problem'; they just wanted me to sign a liability waiver)
- BRP has no stake in Kenda, or agreement with Kenda that requires BRP to use Kenda tires on their machines.
- The reason BRP uses Kenda is that when BRP was designing the Spyder, they wrote up unique specs for the tires and Kenda was the only tire manufacturer willing to make a special-use tire in such small quantities.
- BRP's specs for the Spyder tires is based on collaboration with Bosch (without whose technology and partnership the Spyder would never have left the drawing board), which designs and provides components for the VSS and ABS systems.
- He was not aware of the unusual rear tire wear pattern on the Kenda rear tires, which shortens its useful life, but surmises it is because of the BRP specs, not because Kenda doesn't know how to build a quality tire.
- He is going to pass this concern along to engineering to see if something can be done about it; it's not good PR to have owners upset over rear tire wear and lack of cooperation from dealers.
He also told me something else that I thought interesting. Before going to work for BRP (he was one of those testing and tweaking the pre-production bikes), he worked in a similar capacity at Yamaha. Back in the '80s Yamaha experimented with a reverse trike but couldn't figure out how to make it stable on the road; several of their test riders were seriously hurt trying them out. Yamaha dropped the project, not because of lack of interest in the concept but because the technology at the time wasn't available (ABS and VSS). It was the partnership with Bosch that enabled BRP to overcome those stability issues; the Spyder would not have been possible without Bosch's technology.
One of the members of this forum (who is also one of the leaders of the SRA-Sacramento chapter which hosted the rally), chimed into the conversation I was having with the BRP guy and said that his understanding of the Kenda tires is that for the 2013-2014 model years there was a batch of tires later discovered to be defective in some way (maybe the rubber compound formula), resulting in the unusually short life of the Kendas. He thought perhaps newer tires don't have that problem, as he has over 15k miles on his Kenda rear tire (I think he has a 2016 F3).
Anyway, just to let you know that BRP is going to look into these issues and try to come up with a solution. Meanwhile, they have no concerns about us using non-Kenda tires. Just be aware that some tires may be too sticky or not sticky enough for the VSS to work properly. If so, the owner bears the risk.
Thanks for the info, we have a 2014 and I think we have the bad tires on the bike as the back is worn and the fronts are cupping. We need new tires very soon.
