Thanks for the thorough explanation as usual.
But why make it standard if it won’t be used by the majority of users. Especially if, “This will require some knowledge and understanding of how to shift these without causing damage to the gearbox.”
Two different gearboxes is more expensive to make than one.
As mentioned, the vast majority of people who will be using these cars in a recreational way, will never need to shift them on the fly. 1st gear is still really low for crawling/slow speed technical sections, and 3rd gear is too tall to really use for anything other than an overdrive. 2nd gear will be the best gear to use, and let the CVT work as intended.
I don't know how Speed UTV is going to approach the shifting aspects. I have had a brief conversation with Robby a few weeks ago about this. Robby was considering language in the user manual along the lines of what I said above, that is the last that I heard about this.
For what it's worth, I highly suggested using some sort of lock out feature that would prevent these from being shifted on the fly. That lockout feature would need to be removed for shift on the fly operation, and therefore would void any warranty on the gearbox. This lockout would be a complicated feature to design and implement, so it was decided to move forward without it.
Regarding the aspect of shifting through the gears to improve belt life/efficiency, this is really only something that sound good on paper, but there is no real data to back this up. I have put a lot of thought into this over the past few years, and there are some aspects that are simply unknown until it is implemented.
I do know that the Speed UTV team has been playing around with shifting these as seen in some of the videos, and that part does seem to be working so far. The effect it has on belt life is yet to be seen.
Also, I do not speak for Speed UTV. All I can do here is respond to specific questions about gearbox and front diff that I am a small part of.
