those are 41mm KLR forks in the OEM ER6 (650R, EX650) clamps. his setup is 19/17, but the 19 with tire is not much different in diameter than the 21 with tire. the KLR and ER6 clamps have different centers, so you're looking at wheel spacers and a caliper spacer to make the 21" KLR spoke wheel fit. very easy work.
haven't seen any recent builds using the KLR forks, although bodie1 reports he has a bike in the pipeline using this setup.
i like the 19" wheel on these bikes for a variety of reasons, but that's just one opinion, others vary.
Thanks! I thought it had been done before. The KLR and ER6 clamps having different centers was the key information that I could not find. Sounds as close to a truly bolt on front end as I have found so far.
