Ryker front tires size is Proprietary! Thanks again BRP........

[Peter Aawen]

For the fronts, it looks like Yokohama do an S-Drive in 175/50R16 77T SL that's almost identical in size in all respects except the width, but I haven't been able to get the ACTUAL physical dimensions of the OE Kendas to confirm any physical size differences yet.... and I believe Kumho do an Ecsta SPT KU31 in 165R45/16 74V which is a 'similar in all but width' size too. Both of those are basically Dry Weather Perfomance tires, altho both manufacturers claim that their particular tires have "superb wet weather performance, grip, and hydroplaning resistance".... Yeah, riiight! And without trying very hard I found a whole heap of alternatives for the 205R45/16 or the 205R55/15 rear tires in just about any spec or tread type you might want; 48 popped up on the very first search I tried!! So I don't think it'll be too hard to find a replacement tire for the rear!

So it seems that there are some 'reasonably close in rolling dia but wider' alternative front tires out there; tires that look like they should fit under the std fenders without much effort/modification, but we really need those people with Rykers to get out there & start putting miles on the OEM Kendas to see if BRP's claim of improved tire life & exceptional ride & handling is anything more than marketting hype! Yeah riiight! And I really want to get hold of a couple of these 'new' Kendas to dissect them & see how they are REALLY made.... I suspect that they aren't 'real' motorcycle M/C tires, but just like the Kendas fitted by BRP to our Spyders, they are basically just poorly made lightweight versions of automotive Passenger 'P' tires, the proof will be in the dissection! However, right now we don't have too many Rykers on the ground here in Aus, so it might be a little while before I can convince someone to donate their Kendas to the cause!!

That means it's up to you lot over there - get out there & start racking up the miles on those Rykers! You can't let a little snow or cold weather stop you, that's irrelevent & unimportant in the burning drive to answer these important questions for the edification of all Spyder/Ryker Lovers! Just get on your trikes & ryde, you hear me?! I'd do it myself but no Aussie Rykers have been delivered yet, aand besides, it's over 40° C here again today, so it's just too hot for me to ryde...

it seems that we have to look on the japanes Market .. they have a lot of smaller cars
- found this here for the rear (Price would be Ok)

Does that say 4.4 psi for max pressure?

[Michaelscs]

We don't yet know anything about these particular Kendas on the new Ryker. These tires are different than the ones on the Spyders (same brand - different models), and the Ryker weighs 300 - 400lbs. less than the RT's & F3's. The handling and wear of these new Kendas on the new Ryker could be completely different than our Spyders! Maybe BRP & Kenda got it right this time.

[Peter Aawen]

C'mon guys, if you have a problem with a post or poster, don't start a posting war, just report the post & let the mods handle it!

[IdahoMtnSpyder]

Does that say 4.4 psi for max pressure?

No it wouldn't. I don't see it on the pics of the tires but if that's the number on the tire it's probably 4.4 kpa (kilopascal, metric) which is about 90 psi. It might actually be 1.4 kpa but that seems low.

[Tslepebull]

My tires still have whiskers (****) on them. I hope options develop before I have to buy new tires.

You can make an extension for your regulator torque wrench. and use an extension calculator. https://belknaptools.com/extensions-calculator/

More like opinion since there's no accompanying evidence to lend credence.

Sniff, sniff... I smell burning rubber and see black patches in the distance. Looks like it's tire testing time! Testing methodologies and empirical evidence to tell the tale. How to set up the test is the next hurdle.

Since the Ryker has only one "official" tire, we would need another vehicle with a similar tire size (combined contact patch area), track width, weight, and weight bias... for the minimums. Since the Ryker has no peers, and no alternate/official/approved front tire selection choices (yet), the first variable is the trickiest one to eliminate. If we attempt to use an alternative vehicle with similar metrics, then tire manufacturers, different tread patterns, rubber composition, etc... could be compared against the Kenda's on the Ryker. However, the control vehicle wouldn't be the same, which invalidates the test results.

Maybe we just need to wait for some brave new Ryker owners to mod their front fender assemblies to provide more clearance for alternative tire trials. They will be the brave NASA "X-" class pilots. Good luck and Godspeed to you brave souls... we're behind you all the way!

was thinking of having custom fenders done up for ryker. then i'd be able to change to a better quality tire with no issues...i hope.

[Aufgeblassen47]

The rear tire size 205/45R/16 is not going to be a problem as automotive tires are available. This fact is heart warming since the rear tire is going to go away as smoke quit soon for some riders.

MAYBE if you ride like a pimply faced teenager!

Well, I can say the Ryker is just as touchy with the alignment as the Spyders. I had the dealership perform an alignment at ~830 miles. Here's my front tires after 2900 miles...

Hey guys I got to looking at mc tires on BikeBandit and found some 120-70-16 size tires. These are close to same size except 1" narrower and are rated "S" speed, I used the Shinko SR567 for size comparison. Frank farmer 54

………. Did you actually look at that specific tire ….. The tread is ROUND not Flat like a Ryker's …. The Shinko is for TWO wheel Mtc's …. The traction will be marginal on a Ryker …… Mike

Evidence, I and others here have used that specific tire ….. and IMHO had the best traction of any tire I have tried ….. I'd use that tire in a heartbeat ….. Mike

Kenda 205-55 R16.JPG

Kenda has the worst record for QUALITY that I have ever seen..... From their own specs they are of marginal strength ….. Mike

Not trying to resurrect a dead horse here. But the Ryker front tire situation has, if anything, gotten worse. The S-Drive tire (175/50R 16) that I was considering has been discontinued. And being over 1" wider than the 145/60R 16 Kenda, it isn't going to fit under the front fender anyway. Spacing out the fender like I did with my Spyder isn't an option because the clearance is the same on both sides.

There really isn't anything else out there that comes close enough for me. A 135/70R 16 will go. But the narrower width and taller sidewall are not good combinations. Overall, it's a frustrating process. If the Kenda's I have were decent, then I'd be fine. But they rattled my eyeballs out of the crate and after several attempts to get them balanced, they still shake an aggravating amount. Even though they are brand new, I know my only real solution is replacement.

[Highwayman2013]

I hope a good replacement is found. I’m thinking about getting a Rally.

Well, the stock tires will last a good long time and the wheel's aren't falling off my Rally so I would say you are clear to buy one if you can find one.

[Highwayman2013]

Not a Kenda fan.

[Zoot]

You know, it's not just a Ryker thing. Car tires have gotten much larger in the last years. Some of my friends own older cars, sports cars, for which the OEM tire sizes are no longer available. They are having to go up in size and play with the aspect ratio to try and maintain the diameter.

[Markubis]

Maybe we can hope the aftermarket will come out with a wide fender replacement to allow a better range of tires up front.

[Stephenj37826]

I was looking at the stock fender. If you slot the bolt holes holding them on it may be possible to raise the fender allowing a wider tire to clear.
