Confused about using the up to 2013 engine - rule. If the newer engines are the same 2011 to 2020 can you use a 2015?
Thanks,
Will

I only have experience with the Suzuki, and they used to use a 2 year cycle (I run the 06/07 series) but it does look like the 2011-2020 is the same.

Interesting. Marketing materials show a HP creep between the '11 and the '19 and a slight CR change. However looking at p/n of valves, cams, valve springs, pistons, rings, rods, cyl heads, they're the same from 11-19. Even trans ratios are all the same. The throttle bodies and ECU's have 3 different part numbers over those years but all show that they apply to all model years. Don't know if that's a CA vs. Federal emission vs. EU market thing.
Generally the 600 Supersports don't change THAT much, Honda being notoriously the company that makes the least amount of changes of the 3 which is why recently they find themselves lacking when years back they were on top.
As discussed on the Facebook group. I understand why they only changed the Suzuki to 19 (because most likely whoever wrote the letter only mentioned Suzuki and the board probably didn't bother looking into anything besides what was mentioned in the letter)
Whats ironic is, at least for Honda 13 was in fact the year they had their significant changes which haven't changed since.
I'm sure simply sending another letter in would have them fix the rules to all 3 engines bumped up to 19.
That being said hopefully the results of this year's runoffs might finally easy peoples minds that the carbed engines can still be competitive with the MC engines. At least to some degree.
I wrote in for the rule change because the suzuki motors are the same from 2011-2020. I asked for 2011-2019 because I didn't know if any revisions would be put in place before 2020 was over. Even though the HP numbers show different in the magazines nothing has changed on the motors and ecu other than improved emissions stuff. If you want to do the research to prove the other MC motors are all the same from 2011-2019 I'm sure the CRB would pass it as well. I just have numerous customer cars with the 2011-2019 motors in them and didn't want them to be restricted to only being able to buy 2011-2013 motors.
I get your point. However, every manufacturer doesn't boast the highest horsepower number, otherwise we'd be approaching infinity by now with all the ads released in the last 100 years.
I trusted the magazine numbers I saw with each bike relative to each other, because they came off the magazines' dyno, they also published just how "optimistic" the factory tachometers read. Those optimistic tachs probably sell more bikes than the dyno numbers when bench racing at the watering hole. I know Yamaha had some legal issues over their tachs, Ford has had legal issues over MPG figures, Hyundai, Kia and Shop-Vac over horsepower claims. Until some group like Consumer Reports decides to have a HP shootout everybody (including engine builders/tuners/racers/rules makers) has a vested interest in the outcome.
