Ok newb questions.
So looking at the regulations, the hard minimum for bike weight is 110kg, but the curb weight is listed as 110kg, how do you maintain that at the end of the race?
Combined bike and rider is 186kg which leaves minimum rider and gear weight of 167lbs??? Am I doing that math right? So lets say your rider is 135 in gear you would need to add 13kg to the bike to get to the soft maximum and then be legal?
Pretty disappointing suspension is open. Add another $2500 to the price tag.
Right now our bike is 110 kg ready-to-race, sans fuel. If you ran out of gas as you come into parc fermé, it should weight 110 kg. So, I don't see the issue here.
With my Krämer hat on, I don't have a horse in the race on minimum weight provisions. We just make the bike, and MotoAmerica makes the rules. As a fan of the sport, I have some ideas, and I generally think that the combined-weight approach is the right one.
Your math on the rider weight is correct, and you do have to account for maybe 20 lbs of gear included in that figure. 147 lbs isn't unreasonable for a rider weight, and there's a couple things to note in that.
The big one for me is that you don't want bigger (i.e. taller) kids dieting to get down to dangerous weight measurements. At this age, that has huge consequences developmentally. Athletic anorexia is very much a thing in sport, and something we don't talk about, especially for men and boys. I know two young riders who were on a top MotoGP team and they used to compete with each other on who could eat the least each day, just so they could weigh less on the bike and be more competitive in the class. I won't name names, but it's probably not the riders that first come to your mind when you wonder about it, which only shows how prevalent perhaps this issue is in the professional paddocks.
You are also correct on your math for the soft maximum - if you put 13 kg of ballast on the bike, you don't have to hit the combined rider and weight figure of 186 kg. This means that there's really no reason for a rider to weigh less than 138 lbs or so with gear on. Understand though that your 135 lbs in gear means a 115 lbs rider. That's on the extreme side when it comes rider weights.
Back to something I have professional thoughts on...
The suspension was left open so the riders that have sponsorships with other suspension brands, i.e. Öhlins and K-TECH, can still legally use those suspension companies and not lose those their contracts. We want kids to gain sponsorships, not lose them.
I can tell you that the WP Suspension on the Krämer APX-350 MA is just as good as anything Öhlins or K-TECH can or will provide for the class within the limits of the rulebook. I can also tell you that the support for WP Suspension at the race track next year will be just as good as those other brands.
We are building turnkey race bikes, nothing on them needs to be modified or changed (in fact the rulebook prohibits that), so I think the notion that there's another $2,500 to spend on this platform is incorrect. That being said, I'm sure some teams will make the switch from WP to other brands. That seems like a waste of $2,500 to me, but they can make their choices.
