So we just had 2 2023 Pro R's delivered to the house yesterday. One is my uncle's. Neither one of them will go over 10mph in high or 4mph in low. One has 5 miles on it already and the other 1.5 miles. We've been trying to troubleshoot it. Called the dealership. Nobody knows shit. Going someone here has a clue.

If it isn't the seat belt circuit, makes me wonder if these new machines have a dealer transport mode like automobiles do, where they are severely speed limited. But you said you talked to dealer and they had no clue?

That's interesting, wouldn't you think it'd be throwing all kinds of codes being starved of air so much that it only goes 10 mph? I mean it'd be so rich that it would be backfiring in the exhaust don't you think? I mean I understand the mass airflow sensor adjusts trims for fueling, but the base tables are still there and they just get tweaked with the values of the incoming air. At least, that's how it's worked on other engine management systems I'm familiar with. Maybe these are different?

Either way, it's super weird that both machines have exactly the same symptoms.

Maybe someone with a pro r can go drive without the seatbelt and see if it's the same speed limiter...my gut still says it's related to that.

That’s exactly what happens with the seat belt not buckled but he says the seat belt is buckled. There is another connection under te seat that may be loose like Ebwhite said check for cut pinched wire or backed out pin. Very strange that it’s both units. FYI only drivers seat has the belt switch.

Yeah we bought them in Tennessee and had them trucked to Arizona. Called the dealer in Tennessee and they didn't know anything.

I69? If so I can attest to the fact that they do a shitty PDI (free though). However once you call them on it they act like they don’t know who you are especially from the service department they were zero help with my cosmetic issues that mine had that was most of my disappointment and I 69 but hey I guess you get what you pay for sometimes. My local dealer had to take care of it through a Polaris case number when I called customer service and it was all fixed
