Honda CB400F Vintage Cafe Racer | Purpose Built Moto Builds

With its fresh motor, new tyres and brakes the CB400F is a real joy to ride. A small carbureted four breathing through a set of DNA pod filters with all its glorious ticks and noises. Around town the Green Honda turns heads on every corner, and once the traffic lights disappear and the roads open up getting the CB400F up past 6000 RPM brings it to life. The engine work done has given the CB400 a great amount of usable power that begs to be twisted out of the throttle. I’ve said it before and I’ll say it again. There’s nothing better than riding a small bike fast.

The parts used on this bike are:

- Universal fit Aluminium front fender and Mounting kit:
- LED 3 in 1 Indicators:
- PBM 3 Button Switches:
- Black Box:
- Custom Seat:

That road looked slick. I road a 400f for 15 years, I had faster ones, but that little bike was just so fun to ride, a truck backed over it, or I would still have it.

I've never seen anything like this bike before. It's really amazing to see how much effort u put into it. Keep up the good work.

7 minute ride - zero other vehicles on the road!

makes me rethink my love of my big bore bikes

Tom!!!! Your channel is killing it! God shit dude! We miss you bro! Keep being an all time legend!

Awesome bike and an awesome road! I have an original CB400F from '75 which is gettin a top end rebuild atm. Cant wait for next spring/summer to ride it again.

Beautiful bike man, super clean lines and sounds great too 👌

G'day mate, what a beautiful looking bike and incredible vision you guys had! My old man's got a Navy Blue 1976 400 Four sat in the garage out in the Mediterranean. Said he would never sell it and would leave it to me, bless him. It needs a bit of TLC but would love to restore it to it's former glory but with a Triumph Thruxton-type exhaust set up and change the colour scheme to a subtle brown/tan and maroon leather seat config. Am just too scared on where to send it to, to have it done properly.

A couple of my favorite 400-4 speed tricks:

When you have a couple of worn out clutches, make a new clutch stack from the worn frictions and steels, an extra of each will fit, making for a stronger, longer lasting clutch with the same feel as the original.

If you have the top end apart you will notice that the valve springs are progressively wound, but the heavy end of the springs are placed randomly. Put the heavy end down on both the inner and outer springs, this will give you a few more revs before the valves float. I would always set my valves just a bit tight. This meant that the valves would sometimes not close completely when sitting in traffic on a hot day, necessitating a shut down and cool, but of the three of us that had 400 Super Sports, mine was always the fastest (for a lot of reasons).

Makes me miss my CB350F that I had a long time ago.

[bikerbrinrac]

Wow that's a great looking cafe racer style bike 🏍️👍

[richardwarner]

Boy those primary drive gears are noisy...until that great exhaust note takes over!

[kelstra]

Excellent video. I don't where in Australia this road is but what is surprising is that you didn't come across another vehicle of any description on your road. That has to be some sort of a record.

Love this bike but I don't think those are the stock headers. The 400F header pipes famously sweep down to the right together. They may have been on the bike when you guys got it, but the factory pipes would be different. Unless Honda changed them at some point.

Just picked up my dads old 75’ CB400F super sport. Hasn’t been touched since 87 and wasn’t stored properly so I need to restore everything on it. Tires surprisingly still hold some air though!
Would love to go this route but I have no clue where to start.

[Rasmus_Nylander]

Awesome build. How wide are the rims, and where did you get them ? I need some new rims for my CB400F. :)

[peterroda]

Wonderful job.
Can you tell me how much the wet weight is?

[MrPeterJDM]

Where can I get a seat cowl like that? The link in description shows a 404 page.

[brandonloder]

Could you post a link the the muffler y’all used.
