So recently I picked up this 2020 RMZ-450 for a ripper deal which has left me with a lot of wiggle room to spend cash on it without feeling the pinch too much, so I thought why not make a build out of it to turn it into my dream bike.
It's my first brand new dirt bike and it's really something else without all the stripped bolts and 'personal' touches of previous owners which is all new to me but also means i can't blame anyone when i strip some bolts or do something dumb!
My plans with it are to do my first season of MX racing, have a shot at a few pony expresses, race the Hattah desert race and way down the line race the Finke desert race. So it'll go through a few variations between now and then so hopefully people will stay interested.
I've only ridden it once so far and im pretty impressed with it but also i needed to get the honeymoon phase out of the way so i can start making the changes for the better.
So far I've changed the springs out to suit my weight, put a twin air in it and put some 60mm RHK risers to help put the bars up as i stand at 206cm tall (6'9).
Last weekend I stripped her down and got the bearing greasing out of the way and just familiarized myself with it as I haven't touched a modern 4 stroke dirtbike ever!
So i hope you all enjoy the build ill be taking my time with it and my ears are open to anyone who know these bikes well for any tips or what i should put on it as im thinking putting a PC TI-6 on it in the near future with some dyno time to get it running right!

Also remove the judder springs behind the clutch plates, it improved the clutch and won’t stall coming into corners nearly as easy.
The exhaust adds nearly no power.
I’d say Focus on making it more comfortable and easy to ride. suspension revalve the brake caliper and the judder springs helped me the most by far. I installed an exhaust on my 18 rmz, yosh full exhaust and the improvement wasn’t worth the cost at all.
I do agree on making the bike as comfortable for you as possible. That makes a bigger difference than anything else you do to the bike.

No doubt that ill be getting the suspension revalved i just put springs in it to be able to ride it and find out what i don't like about the stock stuff to then tell my suspension guy.
What about the triple clamps made you recommend them as i haven't ridden it enough to notice a need for them so if you have more experience im all ears!
As for comfort im getting a set of my favorite tyres for it as well as sorting some grips, levers and all those little things to make it best for me im not gonna go past that stuff.
If you notice yourself having trouble with shifting being harsh or notchy, run 20/50 instead of 10/40. We made the switch and it helped a lot on the RMZ’s.
Thanks for the input
The clamps help to soften up the front end some, while helping it track better.
I had a full FMF system on my 2015 (pretty much the same bike) And I also had a vortex ignition for a time. On a deep prep moto track, yeah it was badass. Felt like the power was a light switch and just so fast. But in the woods or a hardpack track, it was almost unridable. One day at the track I broke my FMF at a weld and had to switch back to the Stock muffler, and my times dropped and I was able to ride 30 minutes without getting nearly as tired. The aftermarket exhausts just change the power curve in the wrong direction IMO. I'm back with stock now and love it. Smooth and with a little clutch slip it takes off.
I also put a CRF Front Master Cylinder on. Bolts right up. Love the front brake now.
Judder Springs are a must. Easy to do and make a big difference.
Just busting your balls as a Yamaha owner. Great looking bike
Pit Row
Yeah with the pipe im mainly going for a cosmetic look as i just think the oem system looks a bit average.
Im going to end up putting a suter slipper clutch in it so until then ill just ride with whats in it as it doesnt feel too bad at all but who knows after a few more hours i might take those springs out to test the difference.
Then with the hour meter got the works connection setup and got the tank mount cause why not only to find out it wasn't gonna fit on the front tank mount so i tucked it behind the front plate probably not the best spot in case i bin it but ill just have to find out when it happens.
Going out both days this weekend to the track hopefully get these stock tyres worn down enough to warrant replacement and then find out whats getting changed next probably the motor mounts and a nice skid plate to save those cases from getting too stained.
I have an ‘18 and if I remember it was a bit tight against the tank cover to get it installed, but it works fine.
