Did you get the Dunlops in BC? How much?
I think your sidestand was from Matt Hotch.. or Hott Match customs.... if my memory is working..
You can't find these tires in North America as far as I know. The funny thing is, if you read Sideburn Magazine, there are a number of flattrack racing teams that are obliged by their division rules to all use a specific set of tires, some being these K180s.
Dunlop doesn't list them on their site but does an obscure link to dealers you can contact for them. Most are lsited as not selling to the general public. I called every one of them and nobody had inventory. I checked with five or six of the major flattrack equipment dealers in the US and nobody had any inventory last year or knew when to expect any for this year. This was also true of the Maxxis tires.
Meanwhile, I had built new 18 & 19 wheels; Excell alloy rims, polished stainless spokes (both from Buchanan), silver powdercoated hubs. Trouble now was that nobody makes an 18 and 19 flattrack tire except these. Everyone is 19 or 17 and 21.
One guy finally told me they're made in Japan and I wound up going to a Japanese website (webike japan: I left a positive review in the "good dealer" section). Found them, about $150 a piece and $40 shipping. They arrived today, one week after ordering, by Canada Post. No duties, no taxes, no GST . . . just sign for them.
So I spent a bit more on the tires than I might have. US dealers wanted about $120 a piece and you can guess shipping from California to BC would have been near $75.
I didn't get my sidestand from Matt Hotch. It might be a ripoff of his design but there's an ebay seller who "makes" them in the US, I think about $130 plus shipping. It's maybe $40-$50 more than some of the more generic ones sold by TC Bros and everyone else but the way this one just fits my lines is great for me.
I am trying to get this thing done. Had some health and family issues that slowed things down. Rob (voxhonda) is making me a box swingarm and that's been a bit slow going for him with his cold winter. I am actually into the headlight bucket now, just been making and getting some relay setups made for key switch and H4 headlights. I was going as fast I could then looked at my old wheels and thought they looked ugly . . . may as well do it right and nice.
