Double check all of your fender bolts before riding! Trust me lol. Other than that, Kawi’s are solid! Enjoy it and congrats!

Bar mounts, lower chain roller, tighten every bolt, they seem to work loose bad. Don’t get a FMF exhaust.

Read up on the 1000 page thread on here

Judging by the lack of grease on the steering stem, go through all the linkage and swingarm bearings. Sometimes there is enough grease, other times there isnt. My 21 YZ250F barely had grease in the linkage. Looke more like an oil rather than grease. Also for peace of mind. Di-electric grease electical connections. Even if it may not ever see water at that point, its a 100x getting the connection apart if something has to be replaced.

Rubber side down is all you need to know.

On a side note, I got a killer deal on my son's new YZ65 from Power Motorsports. Would use again!

I've had 3 KX450s in a row. On all of them the same thing is needed:

-lower *and* upper chain roller
-Acerbis chain guide and swingarm buffer (cheaper and better looking IMHO than the TM designs)
-never seize on the chain adjuster bolts

But almost nothing else is needed on this one. These '19-up bikes are soooo good. I don't know what suspension changes were made on the '21, but the '19 forks were solid with just a slight bump in oil level (335 cc). I sold mine in favor of some KYB A-kit forks, but I am still running the stock shock with not even a re-valve.

Edit: the '21 clutch is supposed to be really good, enjoy it!

Congrats on the new ride!

From SoCal vet riding experience, here are a couple recommendations: grease, anti-seize, and loctite that beauty before riding; 116L chain with 13-51 gearing to re-position the rear wheel; slip-on exhaust with stock header is a good way to go (really like the PC and Yosh versions); 110/90-19 rear tire; toss the stock grips (and vulcanized throttle tube) for something more comfortable (there are a few aftermarket options for quicker-turn throttle tubes which also perk it up); throw the white coupler into the holeshot/EFI indicator plug if you want to clear up bar space by removing the entire system; ride it stock BEFORE tuning on the suspension, it will give you a better baseline and appreciation for how close Kawasaki got this 2019+ platform - At 200lbs and with 25+ hours on my 20', all I've changed is +20cc's in the forks with the optional stiffer OEM's springs (5.2N/MM front and 56N/MM rear), coupled with clicker changes and a minor revalve on the shock...Enjoy that beauty


Edit: Add ARC front brake lever to the list if you don't like the pencil-thin stocker.

PS: Is that an 18" rear wheel and kickstand in the dealership photo? If so, disregard the 110/90-19 mention!

Hey man, new to the page. What’s the beef with fmf exhausts? Thanks!

beef up the muffler bracket, and I personally like to get the radiators beefed up as well by icw.

Hey Tim. If you don't have a thread insert kit already, go get some. M6 especially.
I've had all brands and for some reason, Kawasaki has the worst fasteners (specifically the female side) in the business.
The larger (M8 and up) stuff seems ok on the bikes.

I’ve only lost a single bolt (a front fender bolt that I’ve honestly never checked) in the year I’ve owned the bike. I also have never bunged up a thread on my bike, either. I torque everything to spec every time I screw in a nut or bolt, so I suppose this helps keep things from rattling off. If you’re constantly losing hardware or damaging threads, that sounds like user error to me.

How about some photos of that center port CZ you mention in your signature?!

Congrats on the KX450, welcome to the Team Green Family. There's plenty of good info in that 160+ page thread!

I have the Das Motorad article on the bike (with color photos) in a box and I might have some pics in my computer at home (I'm at work) that I can dig out.
