I went back to the dealer to order a rear tire (MT90 150/70-18) and saw a CB1100 Deluxe (was not there this morning): $9,995.

Also a used BMW R9T. Already sat on their Kawasaki 900.

Nice bikes, but I like the CB much better.
Dennis Kirk had the front tire, which I ordered and it should arrive Monday.
Rear was backordered at Dennis Kirk, so I did not order. I was thinking of getting both and keeping their rear as a spare.

Dealer $318.92 for rear, with "free" mounting, including mounting of front from Dennis Kirk.
Dennis Kirk: $141.88 for front
Total: $460.82...not exactly a bargain, but the last time I had a dealer involved in tires it was 2005 and about $325 ($300-350???) for F & R on a Sportster.

If inflation has been ~3% per year, then 1.39 x $325 = $451,so not out of line.

Ah, don't forget about compounding, and I'm not talking rubber or pharmaceuticals. Your assumption of 3% inflation/year over 13 years = 1.468 factor, not 1.39. Remember, everything that goes up by 3% the first year goes up by another 3% the second year, and so on. It's not simply 3% x 13 years. The magic of compounding.

$325 x 1.468 factor = $477 inflated price today

If you paid $460.82, you beat inflation!
