Tyres anyone?

I have posted twice elsewhere in this forum, and neither one is visible after several days, so Iíll try here. Why canít I post links?
The standard Valkyrie front tyre is a Dunlop D254F 130/60 R19 61H radial, a very odd size for a radial. It's in the Dunlop Australia catalogue, but I don't know if anyone imports it. This tyre is available on Ebay, from the UK, so that is one solution. Rear is 180/55 R17 73H, also a radial. To replace that my choice would be Michelin Pilot Road 4 GT.
Then there is the alternative front tyre size 120/70 R19 60V radial, available in several brands. I'd go for the Michelin Pilot Road 4 Trail. The speed rating is higher than 61H, but the load rating is 7kg lower. A tyre calculator on the web (Iím not allowed to post the link here) shows this to be 1.9% larger in diameter, not enough, I assume, to affect the ABS. Elsewhere I have read that relative tyre profiles do not affect ABS, is this true?
There are cruiser front tyres 130/60 B19 61H in bias, like the Dunlop D208, Dunlop American Elite, Michelin Commander 2, Michelin Scorcher 31 etc. My tyre dealer insists that mixed bias/radial on a bike renders it unroadworthy here in Australia. I could find no rule like that, and I think he's wrong. There appears to be no problem with bias front and radial rear. Many bikes come from the factory like that, and Michelin recommends that combination for some bikes. Another such bias front tyre is the Metzeler ME888.
Finally, my tyre retailer suggested a more cruiser oriented tyre for the back, for longer tyre life. The 180/55 R17 size appears limited to sports or touring tyres, but the Metzeler ME888 180/60 B17 75V is close. The tyre calculator says it does 2.8% fewer revs per mile, so the speedo (sensor is on the final drive) would read 97.2km/h where it would read 100 on the 180/55. That might make it more accurate.
So I'm thinking about the ME888 bias/bias combination. What tyres are people running on the Valk?

You can't post links because you don't have enough posts, I think you need 15 or something like that.

Anyway, I'm running a mich commander 2 on the front and pilot road 2 in the back. They feel great and are supposed to last longer than oem. I'll let you know if that's true in another 6000 miles.

I don't know they compare to the 888 but I had metz 880s on my last bike, a suzuki m50. They still had decent tread after 10k miles when I traded it in for my Valk. I don't think it's a bad choice.

I'm more concerned with grip (especially wet) than long life. I might go with the Michelin Commander 2/PR4 GT combination. If I get 10000km (6250 miles) I'll be satisfied. I'm used to about 11000km from Pilot Power 3/PR3 on my Daytona 955i.

I am running
Rear : Michelin Pilot road 4 gt 190 55 17 73W
I swear by these until something else comes along. I get similar mileage to the OEM Dunlop but the wet weather grip is not comparable. With the OEM Dunlop I could spin the read in any gear except 5th in the wet. A lot of fun was to be had. When I tried the PR4GT that was no longer possible. A lot less fun but hey a lot safer.

Front: Michelin 120/70 ZR19 60V Pilot Road 4 Trail
Only got 10000k's or so on that so far. Bit of a flat spot but wet weather grip is comparable to the back (IE awesome) and still has plenty of tread.

If you want longevity on the front then go for the Dunlop D408F 130/60B19 M/C 61H. It has Harley Davidson on the side walls. I also got around 25000k out of that bugger... no kidding. The down side is that it is well... a Dunlop so not that great in the wet and it also had a vibration. For example you let the bars go and they wobbled slightly. No issue when hands on bar tho. That mileage may allow it to sneak back onto my front again tho. I still have to see how fat this PR4 trail goes. If I can get 15000k or so then the PR4T will stay cause the grip is well worth a 10000k hit I think... maybe.

Thanks for the info Shrubbo. I guess the 190/55 gears you up a bit. I'm a little concerned about the 120/70-19 60V PR4 Trail, as the load rating on all the 120/70-19 tyres is less than Honda's 61H specification, thus contravening ADRs. I was wondering too about the Michelin Scorcher 31 tyres, also with Harley Davidson on the side walls. I don't know if they are available in Oz.

Shrubbo's in your corner of the world, so that at least answers one of your questions.

There is nothing noticeable as far as "gearing up" is concerned.

Honda specifies a tire that is $500au for the front and $750au for the rear and have pretty much diabolical grip in the wet. Well they did cost that last time I checked. The PR4T tire seems great and I was a long way from being the first to run them so they are not unknown item or anything that even slightly concerns me. It is also looking like it will easily out last that nasty OEM but your choice

BTW if you really want to be worried a Honda dealers put that Harley tire on my bike without permission because there was zero tires available at the time. Honda Australia said it was dangerous and I had to pull it off... at my own expense (I am not kidding). Honda doesn't know **** and can burn for all I care.

That being said I may still go back to that tire. Huge mileage I got out of that Harley hoop. Something like 25000k.

..and yes, I am in Oz as Turbo pointed out. Can you tell I don't think much of Honda Australia or their dealers? Good thing I love the bike else I would have an M109

Funny you say that, the m109 was my first on my list when I started thinking about upgrading, but I hate suzuki as much as you hate honda.
I paid a little more, but got the better bike. Please excuse the hijack.

haha I spent 2 years dreaming of the 109. Laid eyes on theValk on the net in blue when it came out. Not interested. Spotted it in real life in black and chrome. WTF. Never rode an m109

I preferred the 2015 red, but seeing the blue in the flesh it looked OK, and it being maybe my last chance to buy a near-new Valk, I bought it. I think the black looks good too, but only because the engine is shiny. I don't like that completely blacked out look too much. Mine has the black engine, but the blue relieves it.
I very nearly went for a V-rod, but the Muscle, not the all-black Night Rod Special. The 2010 Muscle in red looks great, and is identical in every way to the current model (just discontinued), including ABS. The Night Rod has pillion pegs located to force the passenger to assume a foetal position, which rules it out anyway.
I'm not sure what it would do to the handling, but I'd like a 240 rear tyre on the Valk, it would look much better.
As far as I can see there was no problem with that front tyre that Honda installed. Bias is OK on the front. What were they on about?
I like the idea of long lasting tyres too, until it starts raining :-)
