the 07 kingpin came from the factory with radial on front, bias on rear..... the replacement bias ply rear tire reads on sidewall " manufactured exclusively for fitment on victory motorcycles".. also i called several dealerships inquiring about replacement tires and everyone came back with the radial on front and bias rear. the vegas is the same way
Front tire is not a radial. Look at the sidewall. If it's a radial it will say 130/70 R 18. The OEM tires on the Kingpin are both bias ply tires. Some bikes come OEM with a radial rear and a bias front but NEVER the other way around.http://www.dunlopmotorcycle.com/fitment-guide/search?type=fitment&make=26&model=805&year=901&submit=
130/70 B 18.... no R... NOT a radial tire.
Reading the sidewall: 130/70 ZR 18 M/C (63W) TL
130: tire section nominal width [mm]
70: tire aspect ratio [sidewall is 70% as high as the tread is wide]
ZR: tire construction type [high speed rated radial
18: rim diameter [inches]
M/C: tire for motorcycle only
63: load index code
W: speed index code
TL: tubeless tire
As for the made for Victory thing.... BULLSH!T
Dunlop made those tires before Victory made motorcycles. The tires on the KP don't even match (one has raised letters, one does not). In fact, the recommended rims for these tires are 3.5" and 5.5" , while the KP rims were 3" and 5" before the 'Stingray' wheels.
Victory and Dunlop have signed a "PROPRIETARY AGREEMENT". In other words, these tires will only be sold to Victory and cannot be purchased directly from Dunlop "OEM ONLY". That way the dealer can phuck you senseless on what you pay for tires. $240 for a rear tire... hell, I get a PAIR of high-speed radials for less than that.
There you have it. All of this information is readily available to you. Never simply believe what you're told and never speculate. FIND OUT.
