You should be able to find fork gaiters for those forks but as far as the plastic dirt shields you may want to look at bikes with similar sized forks and see what shields thay have then maybe you can get a set of them. I would go with a smaller fender. maybe modify the one you have. I cut mine down and it looks good.
ok update time!
I got some more work done. It's been slow going (machining took some time) but good progress has been made.
I FINALLY was able to get the wheel bearing out, and test out the fit of the new ones
new bearing, new axle
some measurements.
The wheel bearings are only supported on one side of the wheel, the rest is kept from sliding into the hub by a machined spacer.
I also got my tapered steering bearings in and measured correctly. You have to space them up the stem the correct distance in order for the stem to sit in the correct spot.
bottom race inthe teer tube
upper tube
lower bearing installed
upper bearing before being packed
and when all is said and done you can still use the stock upper nut from the 450!
also cleaned up the upper triple tree; removing the CBR ignition cylinder mount.
that's all for now

nice swap, good work, but you've got your top dust seal in the wrong spot
They go at the bottom, below the race, and at the top just above that race-inverted, then the nut with the 'cup' thing attached, lock washer (if you want to fit it), then the lock-nut, top triple, washer, then top nut..Would have been easy to weld a tab on the top of the stem to enable a steering lock with the cbr unit?
Love that bare metal tank too
cheers

No I haven't had a chance to yet. I haven't gotten rid of any of the old stuff just so I can weigh before/after when I'm done. I do know that the dual brakes would weigh about 2 pounds less than the original single brakes 8)

I know
I have a dust seal under there as well, but this looked like a cool washer at the time! I can't figure out how the dust seal is going to work under there though since the taper bearings sit so much higher on the top that the seal doesn't really do any sealing ???

Hi Parker!
Nice build you're working on. I love the CB450 especially for it's beatiful engine.
Hope you won't spray it black...
Now just 2 hints (which may come too late):
You measure too small, as gauges have a recess close to the guide.
steel framed bikes.
That's because of the bearings seats unroundness (not remachined
after welding). The outer race of taper roller bearings is too thin to
withstand hence the unroundness will be transferred to it.
The outer race of a roller bearing is stronger and will be deformed
much less. Also it has less friction.
Best regards and good luck!
Sven

Awesome conversion, i love how honda parts spanning 30, 40 years just work together. Im interested to see what your going to do for the brakes, as i can tell there are a few different center bores for the 600 f3, f4, f4i brake rotors i was looking to upgrade the brakes on my 450 to a single 600 f3, f4 or f4i there are the huge 94mm center bores on the newer ones then there is 62mm and 58mm the wheels use a 60mm hub bore so i was gonna use either the 58mm ones or the 62mm ones, the deciding factor was gonna be the bolt circle which i cant find the dimensions of I will keep an eye on this thread and we could probably help each other a little bit

Hi Sven! I hope you're happy to hear that I have zero intention of painting it black, but instead trying to get as much of a "brushed" look all over. I was also concerned with the roundness in the bore where it was welded. I measured it's roundness with a little modification of my dial gauge and it was barely measurable so hopefully there will be no problems.

Hey Chris that would be awesome! My front end didn't come with rotors or hats, so I've been trying to figure out what to do about them. Which bikes have the 62 and 58mm bores? I haven't been too worried about the bolt circle, just so long as the pattern is still 6 bolts...

I haven't figured out yet exactly which rotors belong to which bikes the 58mm and 62mm are off stuff from the late 90's to about 2001, 2002 ive been concentrating on the cbr 600 f4/f4i and the 900/929 and the 1000. Anything after about that turns to the huge 94mm ones which would need a ridiculous adapter made to work.
