I read an article last nite re feathering , more related to track bikes but feathering on the front of the tread block is rebound set to slow and feathering on the rear is rebound set to fast. I presume fast equals soft and slow equals hard.

I just came back from a short 1800 k Snowy Trip , before I left the rear had 3 mm over the TWI blocks .. two days of hi 20 degree temps and full load two the tyre was on the TWI blocks . :o Thankfully the weather and pace cooled . The right hand side of the tyre is now F..ked. Left still has heaps over the TWI . Maybe a good tyre for a track day at PI

Very interesting SP. You would think the principles would be the same on the street, just the speed at which the wear happens would be different :think:

Rear damper on my 07 with a stock Suspension unit is set to 4 clicks out which is one away from maximum according to the hand book , SO i cant slow mine down any more so it looks like new rears every 9,000 kays max. :dance:

I would be happy with 9k km to a Tyre, I have had an aftermarket nitro shock fitted to my bike that is sprung and valved for me, makes the world of difference. Remember the standard rider profile for Yamaha is a 6th Asian man.

ai reckon I am pretty hard on tyres ,, but 9 k is doable on PR1,2,3 so far and just put a PR4 on the rear so lets see how it goes . It feels ok so far. BTW not many get past the FRIJ unless i say its OK :P

My PR3s lasted the whole of the Iron Butt Rally - about 17K in 12 days - from sub zero to over 40C, twisty back roads, interstates, dirt, and that sparkly quartz stuff in snow country. Fully laden and with 43 litres of fuel on board.

Enough tread for the new owner to cover a couple more thousand touring around two up. :clap:

I always bugger the right hand side well before the left ,, maybe if I stopped dragging the pegs and hitting the gas so hard on right handers then I could get more mileage :whistle: :naughty: , but hey who's counting . I always swap the tyres out when I have one spot thats got a smooth line around it ( usually about 15 to 20mm from the outer edge ) regardless of the rest of the tyre cos I figure thats the part I ride the hardest and thats where I need grip. $300 a rear is cheap insurance I reckon . :grin:

Dunno how this PR4 is gonna go tho ,, the sipes dont run anywhere near the edge of the tyer unlike PR2 and 3 . A mate reckons you shouldnt be that far over in the wet ! :violin:

My 1st set of PR4's gave me 13,000kms now I have PR4 GT's, they feel better when towing the camper trailer as well as solo. Will let you know how many km's I get out of them.

Australian road surface is generally much harder on tires than USA surface . Temperature of road surface and how coarse the surface is has a real affect . Over a certain temperature and coarseness tires wear dramatically its really an exponential curve . Wear on one side is due to the camber on the road to help drain the road surface .
On what I have read over the years front tire cupping can be reduced by using a higher front pressure and less hard late braking . I have seen improvements in tire wear on several bikes by raising front tire pressure , but if you are riding hard and fast tire wear is one of the costs you must pay . I generally run 42 psi in the front and rear but Cold wet riding I may lower it a bit . By the way on some bikes a fork brace can improve tire wear ,but I'm not sure an FJR needs one but if anyone has used one I'd like to know their experience .

Just replacing front brake pads and lube on rear suspension ready for Tassie in March labour day holidays. 58000 klms and front pads not half worn cept the rear linked one which was down to about 2mm ,, ( don't forget I got not control over the clutch so back brake gets a work out doing slow stuff) I replaced the rear tyre about 9000 kl s ago with a PR4GT - and haven't been happy with the feel of it but it still has about 2 mm over the TWI on the right hand side . The left side is almost new , I am impressed with the mileage but still find the carcass to stiff even at 38 psi rear. So new standard PR4 coming up before 10 March cos the rear certainly won't last 3000 k in Tassie . Just on a side note I've always found the FJR tends to push the front end a little so recently jacked up front pre load to no lines out and backed off compression / rebound damping bay few clicks and Lo and behold it seems much better . Next for the ores end and we be right for another 50,000 klms.
