XS RIMs question, what's up with Radials???

[MindWebs]

i'm posting this here because i'm not going to be using them on a xs11.

i'll have a xs11/750/850 19" front rim and a 17" xs11 rear rim

I will be mounting them on warpig, 1981 xj750 Seca.

a little creativity required, i have 99% of the asselmbly figured out allready.
(it's good to have parts bikes)

My question is: was the xs1100 radial incompatibility due to the rims or the frame geometry?

i would like to load radials, because my "unique" application i have very
limited tire choices, and the greatest share are radials.

i know most of you will see my modifications as odd, last summer i did alot of
off-roading with a set of avon distanzia tires(bias ply) and my only complaint
was the tires wore down fast. might have to do with higher weight and horse power then they were ment for.

the tires i want to load on these xs11 rims are continental conti trail attack 2 dual sport tires which i believe are radials.

the main reason for my modification is money, or lack there of.
i've picked up parts bikes over the years for very little money.. and now i'm
trying to make an adventure/off-road capable machine, i was at the international bike show a few weeks ago and looked at the price tags....

14,000-24,000 with all the bells, whistles, gaurds, shields, and skid plates, cases



maybe some day a manufacture company will make a bike for me....
cast rims
shaft drive
4 cylinder (xs/xj style)
off-road ready
comfort for a 6'1"rider....

not likely...

but then would i be able to afford it??


Thanks in advance for the help/information!!

No incapatability runnin' radials on the XS's. Street tire options don't exist, as far as a matched set or I'd be runnin' them. Your style of tire, should'nt be an issue either.
My ST didn't use radials when new either, but 98% of ST1100 riders use them including myself.....have been for some 9yrs. now.

radical radials.

i tryed radial michelin commanders on the xs11 and they feather edged badly
and the front "wobbles" side to side at high speed.

i had heard some chatter over the last few years about xs11's not liking radials.

just looking for some technical insite on this before i drop 2-300 per bike on tires.
(both seca and xs11 are past due for new tires)

now....that being said...

yes i have set 2 buddies xs11's up with avon venom fronts and rear dunlop E3's
both of which i believe are radials. (which will be fine for my xs1100 but won't help me on the seca)

and they work very well at all speeds.

so is there a diference in the carcass design? or belting or ???

[motoman]

Differences are both with belting and carcass design. Alot of bike radials do NOT play well together. Bridgestone/Dunlop come to mind(BTDT). Bridgestone bike radials use a '0 degree' belt design unlike some others, and only play well if a matched set. Radials do tend to show cupping from braking over a period of use, but the max. shown p.s.i. for that particular tire helps to reduce that cupping.

[MindWebs]

Well...

the conti attacks are a '0 degree' belt design but i'm hoping that what you're saying
is that they just need to be the same "type" front and back = matched set.

and set to proper (tire spec.) air pressure, not yamaha book spec.

they should be ok.

that being said, yes, i am aware that bad wheel bearing and streering head bearings
will play havoc with with tire balance and runout. and all bike components must be 100% to have a "happy" bike the list of things that can screw up bike geometry are fairly lenthly.

i'm not saying my bike is 100%
but i do try to maintain it the best i can.

Would not concern myself with a conventional balance. I would add an 8oz. bottle of Rde-On to each wheel. Balances and gives immediate plug of any puncture without air loss to tire. Been using it in a couple sets of tires on my ST for a few yrs. now. Tires wear more smoothly with less cupping, plus it's good flat insurance if a long way from nowhere. Look up RideOn.com..

Modified!

Contraire! Not odd to me. I like what you are doing, improving the go anywhere all purpose usefulness of that Seca. Last paint job I saw on it looked good and communicated a serious purpose, bike matches bags.

Have fun. Go your own way. Modify it to work for you where you want to ride it. Go for it...Knobby tires, long travel suspension, skid plates, protection bars... Enjoy it, and if you happen to save $10,000 XSives everywhere will applaud you.

Sorry, I do not have experience using radial tires in applications you ask about.

Good luck wrenching.

it's more fun in the dirt

Thanks!! Brent

some day i'll be smart like you and be smart enough to have a "few" bikes for
whatever i feel like riding that day

it's a slow evolution, of seeing where i want to go and what the bike will handle..

it was originally designed to be a track racer (rocket) so i've been taking my
sweet time, because i may find a point where i cross the line of geometry.

i would perfer to not over-step the line to the point where i can't pull it back from
the brink of oblivion..

besides...

there has to be something better then the (highly) overdone bobbers and cafe racers.

what shocks me it that i haven't heard about anyone switching parts from an 11
to the XJ650/750's, i'm pleasently suprised how interchangable they are. (barring cosmetics)
