    Oof, that's the size I got.

    I believe the stock tire diameter is 26.10" and the 120/90/18 D606 is 26.80". I wish Kawi would have just used metric sized tires...

    Stock size is a 120/80-18 which would give the smaller diameter.

    KLX300 is going to be the next bike I purchase. I don't suppose there's a way I could get the black frame and forks with the green plastics? I don't care much for the camo. I suppose I could have it painted.

    I got the closest size the 606 came in to the OEM size.

    Are you interested in getting a set of green plastic?
    I took the green off my bike the day after I bought it. Replaced it with a used set of '09 red plastic.
    I'll be happy to trade. The '09 isn't running right now, but I'd like to have a set of plastic for when I does get going again.
    PM me and I'll send pictures of the plastic. (phrasing it any other way makes it sound lewd.)

    If it doesn't bottom out you're good to go.

    I run a 606 120/90-18 on my 2007 KLX250s/300 all the time with no problems.

    And you don't want to change the rear shock preload to lower the bike.
    The preload adjustment on the spring is to get the sag correct so the shock will work properly.

    I am not sure about clearance on the second gen chassis, 2009-date.

    If one wants to lower properly it should be done with a travel limiting spacer in the shock. If links are used I believe the suspension will travel a shade further and likely hit the inner fender. But I am bot sure of that.

    Probably should hold off on that for a bit. It might be next spring by the time I purchase the bike.

    I'd suggest looking into vinyl wrap. Should be pretty inexpensive and reversible if need be.

    What size tube do you guys run in your 120/90-18 D606 tires?

    If you look at tbe boxes you will find some will list sizes, some will range from 3.75-4.50 in. and 100-120mm. I know this from about 22 years in a motorcycle shop, selling bikes, parts, and accessories. Just go look.

    Surely I'm overthinking this whole tube size thing but I found that Metlzeler and IRC list recommended tire sizes for their tubes. I decided on the IRC HD tubes (T20076 Front & T20057 Rear). While IRC doesn't specifically list the 120/90-18 in the HD tube they do for the standard tube. They don't list a HD tube for that size tire.

    Finally got some hand guards on my KLX. It probably would have been much easier if I’d have bought a new handlebar.

    Looks good! How was the install?

    The install was a bit of a pain in the ass, to be honest. I found after cutting off the ends of the grips, that there are bar weights spot welded into the ends of the handlebar. I had to use an angle grinder to take off 1/8 to 1/4 inch off each end. That took care of the welds. I then used a punch and pushed the weights further into the handlebar. Then the parts that are supposed to expand in the bar ends don’t really expand enough. So, I do need to address that. I will address that whenever I replace the handlebar some time in the future. It’s okay for now.

    If you plan to do hand guards, be prepared to either use an angle grinder to trim off the part with the welds, or to use a tap and dye to be able to bolt the hand guards directly to the bar weights.

    Or, better yet, maybe just invest in a different handlebar.

    Thanks. I want to get hand guards but am a little apprehensive about the install.
