Whoohoo ! Just got a brand new Heiden tuning seat for £160 shipped.
Made in Taiwan, so I'm assuming that this is the same seat that XS650.com sells.
Price from Heiden is €246 plus shipping, and I think that VAT would have to added at 20%.
It's very good quality, but still not as good as the Yamaha original, unfortunately.
I've also bagged what is apparently a Diablo Cycles seat cover for £30. Also made in Taiwan, and looking identical to the cover on the repop seat.
Made in the same factory in Taiwan ?
