Would love many times over to have a Baja Ron quality dealer out here in the west.

There were many reasons for the change of the site software, the biggest was security. The age of the old software also meant no server updates for certain programs. There are many benefits to the new software, one of the biggest is the mobile functionality. Ill fix up some stuff in the coming days, we'll also try to get some of the old addons back or the data imported back into the site like the garage. To create a thread or to reply with a post is basically the same as it was in the prior software. The default style of the site is light colored, but i temporarily added a darker colored style, to change you can find a link at the bottom of the site.

Vredestein make several models of tire. Which one did you chose for the bike? In what way did your ride improve? Reduced hunting, softer ride?

Vredestein fronts are a firmer, more controlled tire. No car tire will provide a softer ride than OEM Kenda/Kanine.

After riding on various car tires on my 2020 RTL, I traded it in on a 2025 S2S with the XPS Roadster tires. The front tires were promptly switched back to Vredesteins at the 42 miles it took to get home from the dealer! I'll run the XPS rear tire until it's worn out (maybe) and then put a Vredestein on it. The XPS tires may or may not last longer than previous Kendas, but believe me the handling is the same crappy looseness. It's obvious there is still no sidewall strength.

I'll look at it tomorrow and let you know.
I'm not looking for a softer ride. I want to know that when I go into a curve that it will stick!
The General Altimax I had on the first Spyder, an RTL, gave me confidence that it would stick. The Kenda on the rear of the RTS didn't!
The Vredestien I had put on yesterday felt really good today, but I only ran it 19 miles home.
And I have to say, I really miss BLUEKNIGHT 911!
I'm not looking for a soft ride, I'm looking for a tire that sticks! And I wouldn't put a Kenda on my mother-in-laws vehicle! Total crap!

I replaced my '23 RT Limited with a '25 (don't ask), and the Kenda tires are different. As others have said in this thread, they are now the Roadster XPS and the tread pattern is very different to anything that I can find on the Kenda site and they are different than the tires on my ex-2023.
I went to check my pressure on my first ride after picking it up from the dealer. They were around 40 Psi on all 3 tires and I figured "idiots at the dealer". I brought them down to 20/20/18 and I couldn't turn the steering even when riding.
The side walls have "maximum pressure 44 Psi at cold" on all 3 tires. Usually a tire states the maximum pressure around 6 psi over recommended, so I brought them to 38 psi, but it still was sloppy and I found the pressure that works best is 42 all around.
Does anyone else have a 25 RT Limited, and if so, what pressure do you use?
The label under the seat still says 20/20/28. I called the dealership and they were as surprised as me, which means they didn't even check the pressure when they uncrated it.

What's the Max load for the tires??
It should be in the same block of text as the Max pressure - that block usually says "Max Load xx lbs/yy kgs at Max Pressure zz Bar/44 psi.
It should be in the same block of text as the Max pressure - that block usually says "Max Load xx lbs/yy kgs at Max Pressure zz Bar/44 psi.
Remember that's the tires' MAXIMUM LOAD, and that Maximum pressure of 44 psi is only necessary when the tire is carrying that much weight! Most of the time, your Spyder's front tires are probably only going to be carrying about half that weight, if that!
So a quick calculation suggests that given the above, even the OEM recommended pressures for your front tires are juuust a little high for the weight they're carrying, and a fair bit too high for the rear tire, which will possibly be good for lighting it up & letting some of the smoke out; but regardless, running that pressure in the rear is good for BRP, cos it'll wear out the middle of the rear tire fairly quickly and you'll hafta get a new tire!
So your new front tires will likely be grossly over-inflated running at 42 psi; and despite how easy it'll make it for you to turn/steer due to your tire's contact patch at that pressure being so small that there'll be minimal resistance - and minimal traction too, at least in the odd moments the tires will actually be in contact with the road surface! 
Meaning that besides the safety risks you'll personally be running and those you'll be causing and putting the road users around you to, you will also be doing all sorts of irreversible and nasty things to the tires themselves and to your Spyder/it's suspension/any dental work you may have, given the sub par ride, handling, wear, and traction, et al by running them at 42 psi!! 
Think of an 'over-inflated balloon' and how one of those might 'roll' easily on any surface... but also how it will bounce & skip a lot at the slightest bump, as well as bursting at the slightest provocative projection!

But it is your Spyder, so if you really want to...
Still, I'll be very interested to hear how long the Kenda Roadster XPS tires will last like that, and it'd be quite interesting to see the results of a tire contact patch test, say, by putting a broad band of chalk mark across the whole width of the tread, like a 6" wide strip right across the tread from halfway down the outer sidewall to halfway down the inner sidewall and then riding for maybe a hundred yards before looking at it/taking a pic of the tread and what's left of the chalk mark & posting it here??

I traded in my 2020 RTL on a 2025 RT S2S. I kept my front wheels with Vredestein's and put them on the 25 immediately. I had no choice but to leave my Vredestein on the rear, and made the decision to ride out the (still crappy) stock Kenda XPS rear tire before I get another Vredestein. I do regret that I cannot switch out the rear tire immediately. I can definitely feel the difference in the rear tire, it just wants to squirm around in the twisties, where the Vredestein is like riding on rails. They can market the "new" XPS Roadster tires any way they want, but there is still no sidewall strength in them regardless of possible longer tread life.

It will be interesting to see how long the center of the rear tire lasts if someone is willing to run it at these pressures (32-42 PSI). There is no saving the center of the OEM Kenda's regardless of tire pressure. But running this high is likely to exacerbate excessive center tread wear.
