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.
Better tires

How true? :dontknow: That ^^ stuff is basically a crock!! :banghead:
All Spyder/Ryker's Safety Systems are designed to work REGARDLESS of what black round things might be fitted to the rims & regardless of how sticky or otherwise they might be!! You do need to stay within about 20mm of the OE Spec ACTUAL Rolling diameter to avoid 'limp home' codes & failures due to the sensors reporting results outside the expected parameters, but these systems have to be able to handle the 'out of the ordinary' wide range of potential variations & traction changes etc that can occur thru running on different road surfaces, different conditions, changes in ambient temps, tires losing pressure thru slow leaks, tires overheating, tires failing, and a whole shed load more!! If all those features mentioned in that little exchange above COULDN'T handle any & all of those changes safely and without without issues, then they wouldn't be fitted to any modern vehicles at all simply because to do so would be WORSE than pointless having them there in the first place! :gaah:
In my experience and that of many others too, pretty much ANY reasonable quality auto tire within that 20mm rolling dia size & run at an appropriate (lower) pressure for the lighter load the lightweight Spyder/Ryker is going to be imposing on it is likely to work significantly better than the OE spec &/or any other Kenda tire!! :thumbup:

if its the same size as stock the computer doesn't know any different.its round and black like he said.those are odd sizes though.and mine has a ton of weight on the left front.makes me think the stock tire is nothing special.just my .02.
That's ROLLING DIAMETER RICZ, and it came from the people who designed & make the VSS our Spyders/Rykers run; so it's an increase of less than 1" in overall tire diameter.... 
which is really not that big a 'fudge factor' in the over-all scheme of things for safety systems like ABS, Traction control etc when you think about it. 
ESPECIALLY when you consider that the nominal size shown on any tire's sidewall is just that - NOMINAL (ie - in name only!) and that even if you fit an alternative tire that has exactly the same Nominal Size printed on its sidewall, that tire's true size may only be vaguely related to the size on the tire's sidewall! :lecturef_smilie:
I have seen some tires that had a NOMINAL size printed on their sidewall that was ACTUALLY almost 50mm or 2" different in their true Rolling Diameter!!
Later Edit: Off the top of my head (so don't take my recollection numbers as necessarily being correct, but they should be good for explanatory purposes! ) IIRC the OE Spec Kendas are a 'fairly small' 29" dia tire, at least on the rear; so a tire that's anywhere between 28.3" dia to about 29.7" dia shouldn't be outside the capabilities of the VSS to handle, just so long as you try to match any size change on one end with a fairly similar change on the other end. And I can tell you from first hand experience that variance of anything much more than 20mm between your front & rear rolling dia's IS very likely to produce some adverse effects! :shocked: However, do bear in mind that your speedo will most likely be showing you as travelling at a fairly optimistic speed with the OE spec tires fitted; so when your speedo says you're doing 80mph on the OE Spec Kendas, you are more likely/possibly going as slow as 72-73 ish mph, and the odo will be showing you as travelling more miles than you really have (which could be good for your fuel economy figures tho! They'll be optimistically wrong, but looking good! ) So, if you do fit tires with any difference in rolling dia to that of the OE Spec Kendas, in the interest of keeping that 'speedo error', 'odo error', & your actual road speed somewhere within reasonable bounds of everyone else on the road, but not ever letting the speedo show that you are going any slower than your 'true speed', you might not want to go much different in rolling diameter with your alternative tires without making some effort to correct the speedo/odo readings and bring them back to within cooee of the Internationally Agreed & Locally Legislated/Mandated allowance of 'showing a max of 10% faster than true but never showing a speed that's ANY slower than true!' :shocked: Without taking any other speedo correction action, increasing your tires rolling dia just a little will probably help make your speedo a little more accurate; but going much smaller in rolling dia will most likely make you a rolling road block and a hazard to yourself and other road users despite your speedo telling you that you're going faster & further than you really are!! :lecturef_smilie:

If you have OEM Kenda's ..... it is well known that they have possibly the WORST record for DEFECTIVE tires, and for various reasons ..... Mike :thumbup:

For the rear tire there are a lot of car tires, with standard dimension to choose from. I will just get a tire from any well known quality manufacturer, and Im quite sure it will be far better than the Kenda.
For the front tires on the other hand, I have not found any good options. All Ive found are similar, but not the same dimension, of "spare tire" type, with lower speed rating etc. And in that case Id prefer a Kenda. But hopefully there will be some other options once the fronts wear out.

Let me ask a question. What are the OEM Kenda's doing that everyone hates? There have been questions about different tire options since the Ryker was introduced, long before one could have worn out and needed replacing. As far as that goes, I haven't read of anyone wearing one out yet. So is this just a general dislike for the Kenda brand or are they actually doing something that warrants this distrust? I'm probably riding mine differently from other people so maybe that's why I'm missing what everyone is talking about. I ride mostly dirt roads and when on the street I don't ride aggressively or fast and personally don't have any problems with the OEM Kenda's on my Rally. So if someone could just explain to me what the tire is doing but all I hear is "I want a better tire". Not trying to sound like a jerk but sincere in what it is I'm missing.

Personally, just based on my riding, I cant judge if my Kenda tires are worse than any option. All I know is that Kendas are not well liked on this forum.
However, they are also quite expensive if I buy one from my BRP dealer. While car tires in the dimension of the rear tire are rather cheap. So even if the quality is the same, I'd take a quality brand car tire any day of the week.

Sorry *** but "various reasons" is not an answer. What I'm looking for is 'not good in the wet', 'too noisy', not a smooth ride' … just what it is you don't like about them.

" High Defect rate " .... which has little to do with " ride " quality. ..... and what's with this " boy " cr*p ..... that's a term Racists are fond of using ..... Mike ( @ 73 yrs. ) :spyder:

So if you change the rear to a hankook or toyo or whatever. But what about the front tires?

I might be the only one here who likes my Kenda tires, but I still wish there were options. Mine have taking many real beatings with pot holes and bad roads. Lots of rain, they don't have much ware after 15,000 miles and are wearing even. I don't see any facts here other than hear-say. No first hand data.
