I think i found a glitch in the matrix. Lol So forgive me if this has been talked about before, i tried looking up mention of this on this forum and on the internet but have found nothing. So here it goes, laugh if you want, i could be wrong, but im pretty certain portal hubs for the Honda Pioneer 700 will fit the Pioneer 500.... Maybe this is common knowledge to some of you, but i just figured it out for myself. My wife has a 2015 Pioneer 700-4 and i have a 2016 Pioneer 500. I park our sxs's next to each other week after week and got to noticing the front end and rear end parts look identical to me. I started looking up part #s on partsfish.com and some are the same and some are just one digit off. I figured the best way to tell if p7 portals will fit the p5 is if i park both machines next to each other and see if the axle splines are the same. The p7 cv axle plugs into the top of the portal box, and you move the p7 hub down to the bottom of the portal box and mount it on a splined shaft sticking out the bottom of the portal box giving the P7 a 4" lift and 30% gear reduction. That being said, if a P7 hub will fit on a P5 axle, that means a P5 axle will plug into the top of portal hubs meant for a P700. So i spent about 4 hours unbolting and bolting on hubs, knuckles, axles, etc. I have come to the conclusion that it will work. I did the parts swapping on the passenger front and rear of the machines. I did notice that the rear p7 knuckle has a slightly different sized bearing to allow the slightly thicker hub to slide inside the knuckle. The inside of the bearing has a bigger inside diameter to allow the thicker hub to slide in. All the other parts seem to be the same. The front and rear knuckles seem the same compared side to side and with measurements taken from every angle i can think of. So forgive me if this has already been talked about, but there ya go. I think the p5 probably has the least amount of aftermarket support compared to other sxs's so i think this is pretty cool if im right. According to @Nick1997 super atv has portal hubs for the pioneer 700, they just dont list them, you have to call them. He also mentioned another company that has them but i cant remember the name. It was in the thread about Pioneer 700 portals. Well if you can think of anything i missed please feel free to call me a dumbass. Cunstructive criticism is welcome! Lol Sorry for the long post, heres some pics i took of some of the parts swapping.
