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.

I'd be just guessing...
But you've got the swingarm and rear brake stays, to worry about! :shocked:
(And we haven't even mentioned the drivebelt yet!)
But then; I haven't looked all that closely at it...

As a tire shop & spyder owner i would not recommend using the kumho ast. kumho is one of our house brands & are good tires, first the ast is being discontinued, second it is an all season tire & i don't like to mix a/s & summer tires on the same car & more so on a bike. the load index & speed rating come up good but if the ground were wet or you go through a puddle there could be some problems on under steer. ABS braking system requires the same type of tires to work correctly.
For the computer to work correctly the rolling circumference for front & rear should be within 3% of each other.
Unfortunately i can't get m/c tires but i still will stay with the correct ones for my bike. 2013 rt-s fully fully loaded, just got it in May of this year.
My wife & i wear full riding gear & i take no chances with a bike.
I bought my spyder because my wife & i believe it is the safest motorcycle we have ever seen & to save a few dollars i won't compromise.
I am doing my wheels color matched pearl yellow to my bike next week, full yellow with cnc/brushed face. Pressure 15f 28r 76 torque.

P.S. we can mount & road force syders just can't get the tires wholesale. I am also looking for spyders on long island that want to ride on sundays.

"ABS braking system requires the same type of tires to work correctly."
:shocked::hun:
There's really nothing magical about ABS... it merely senses wheel lock-up, and applies braking forces to the affected wheel(s)... :dontknow:
Noboby is saying that you have to use something other than the Kendas...

Why is that? On my GL1800, I run a michelin Primacy Alpin run flat winter tire on the back, and a Bridgestone G709 on the front and feel it is one of the best set ups for traction and safety. There are many that run differeent brands, and even types of tires from front to rear with no issues depending on what they are looking for.

I am just going to say this.....what you are running is dangerous, i would never run it for myself, i would never let a customer run that mix on a car
nor would i allow my guys to install it. I play it cautious. if you want to do that set up it is not illegal for you to do it but it actually is for a tire shop
or m/c shop to install that on the vehicle, we are supposed to know better & we would be liable.
It is your bike & you can do what you want, if you crash it really won't affect or bother me too much. It would be nice if I was wrong but as my
employees know when it comes to tires & wheels i am very rarely ever wrong!! My expertise is on car wheels & tires but i don't expect there to be
much difference on handling characteristics with m/c or spyders.

I was under the impression that you needed to put the same manufacturer's tire on the front & rear of a motorcycle "and" the same front & rear specific model of that tire to ensure the same adhesion to the road in all conditions. Failing to do that could easily result in handling problems & maybe a fall off the bike.
Caveat:-I'm no expert here, it's just what I've read in magazines over the years.

We've all read stuff like that...
I tend to take most of it, "with a grain of salt."
On my GoldWing; I ran Dunlops up front, and Contis out back... the only thing that it ever did, was make me grin!
I suppose that you could get into a situation where two vastly different tire profiles; might make the handling a bit... wonky! :yikes:

Yes, you should always put tires with the same tread design & specs on all points of a car & bike, I personally will match front & rear with same
brand & series tires. As for changing brands and such use the same specs ie. load rating, speed rating or you compromise the full handling characteristics of the vehicles design. Meaning the bike comes with an 'H' speed rating so the minimum you want is the h but you can put a v, w, z or y on since they exceed the h & it is recommended all tires have the same speed rating. as for the load index any car tire you would find would handle the weight of the bike but since the load index of a car would be much greater then our spyders i would expect the tires would not feel the same on cornering and won't have the same flex but would probably give much better mileage & be cheaper.

I am still looking for riders on long island!!
Hi,
Okay so the short answer is.... better wear on the tires. I think it is awesome how you gathered the facts and are pursuing the matter. I have learned that there are not many people in this world.... like you... who care about others... enough to provide feedback. Feedback changes things and makes life better... and in this case safer. I try to do the same whenever I can. Thanks you so much.
Please let me know what you find out.

Good luck, and we're waiting to hear how they respond... :thumbup:
(I had heard it mentioned elsewhere, that BRP got some "bad" batches of Kendas... :shocked

I would complain to your dealer.
My 2010 can -am RT S had 23,000km on it before I got the OEM rear tire changed and it was just down to the wear bars. I uesed another OEM rear tire
the front tires still have lots of tread left.

Out of curiosity, if anyone gets the opportunity, could they weigh the stock tyre vs a car tyre? particularly the front ones. If bike is 2 ply and car 4 ply could the reason be to reduce unsprung weight and to allow more flex to alleviate strain off the steering components? (At the expense of longevity).

I kinda like the tread pattern front and rear of the Kenda tires and the front tires I'm gonna keep till there worn , how ever the rear tire is having a very short life on the rear of my bike :sour: I really can't fault the tire to much I'm hard on it , I do wanna try the Kumho tire just to see if it will last any more and if it doesn't it doesn't. I like riding the bike the way I do and have fun doing it. I did notice that the rear tire size is getting harder to find and the 15 inch front tires don't have a lot of choices either.

Rear...
Front...
How do these Yokohama 205 55R15 compare in real world width to the oem Kenda? I know the Yoko S drive tires run much wider than the size numbers suggest. Any chance you have the kenda to shoot a side by side comparison shot?
I also see nothing in a size close to the 15 inch fronts. Would really like to run GOOD tires such as these.

I ran the Kumho.
Does it wear better? Not by much. I got only 1000 more miles out of it as compared to the Kenda... But I ride pretty hard. Others have seen a mileage bump out of the Kumho. It does wear evenly across the tread though.
That said, and I think this is important. The Kumho was pretty crappy in the rain once you got a little wear on it. It was also greasy on wet roads. For running around and general touring it was fine, but you had to be careful in the rain.
I'm now running the Toyo Proxes 4. Has been the best tire in all conditions. It is very sticky - far better than the kenda and Kumho on dry roads and I have yet to float it in any standing water... and I ran at speed in that nasty storm at the owners event last year in Maggie valley. Only problem is the Proxes 4 is discontinued. I love it so much I bought three more as I could find them. There are still some places that have them... They are more than the Kumho... I think I paid $120 delivered. If you can find one, buy it. There are plenty of us running the Toyo now and we love them.
Next set of fronts is going to be Bridgestone Potenza RE-92's ... Firefly is running those and they are awesome in the rain. They don't look aggressive, but at the end of the day who cares? I want a tire that performs.

I did not weigh them on a scale, but I did do a side by side comparison when mounting the new car tires. It was obvious the car tires were heavier. On my old 08' GS I switched the fronts to the Altimax tires and the difference was only slight. It would have taken a scale to detect the difference. On the rear I switched from the Kenda to the Falken, not the Kumho, and that tire seemed to be several lbs heavier. I would suspect the same would hold true with other brands because the Kenda is built very lightly, which I suspect is why they seem to wear out quickly.
I don't think the design of the tire has anything to do with unsprung weight or alike, I'm sure it has to do with costs. The front end of the Spyder is structurally almost identical to their quads and those tires weigh a ton (or tonne :joke
.I will say that based upon my previous experiences, when it comes time to replace the tires on my 14' RT I will buy a car tire without a doubt.

I can almost understand why on a car this is true since ideally their handling is designd to be neutral in that both ends lose traction equally, and are therefore neutral in handling. Cars are regularly driven in a controlled skid. On a motorcycle there is no advantage since if either side loses traction you have a high likeklyhood of going down. I would think that any setup that gives maximum traction to either end is better than matching inferior traction front and rear.

With the many documented failures of rear tires on these large motorcycles, I believe I am using the least dangerous setup for a gl1800. The only change in handling is a distinct increase in traction at the rear. This does mean that the in slippery conditions the front will tend to push first as opposed to the rear coming around, but either end slipping is a bad thing, so improving the grip on eithewr end is an improvement.
On a car I agree that handling can be adversly effected if one end has much greater traction. This is different since the loss of traction is not as big a deal on four wheels, and is much easier to recover from. Even saying that I still feel much safer in winter conditions with my studded Gislavid Nordfrost 3's on the front only of my Altima, than only All seasons all around. Obviousley 4 winters are the best, but oh well.
