I've never really spent much time on the cosmetics or aesthetics of the 450. I had big plans for a cafe style conversion at the start, but the need to sort out a number of things mechanically first slowed things down to the point where the character and looks of the bike began to grow on me. A couple years on now with the bike running well (looks for a large solid piece of wood to touch..) I have a hankering to make one particular change.

I first saw this Norton in the film 'One Week' a long time ago, and thought it was a great looking bike.



The seat really does it for me - a big contoured saddle for the rider, which tapers aft into a nice little racing hump. I think it works particularly well with the lines on the Commando - especially the way it flows into the tank and drops back to the shortened rear hump.

Is that shape achievable on the 450 do you think - either through reupholstering the original seat-pan (preferably) or going down the aftermarket route ?

My Dad used to pull seat covers off and use an electric carving knife to contour the foam - once for my 5' tall ex-wife to learn to ride on first a CB400F, then again on her CB650 later (shorter shocks on the 650 as well, along with thick-soled shoes) and it worked out well for that purpose. He just re-used the stock cover, pulled down more where necessary. (sorry for the grainy close-up of scanned photos)

Since the tank shape is a little steeper slope on the 450, it might be more difficult to achieve that look... but it certainly does flow well on the Norton, it's a great match

Anything can be done with enough time/money/skill. I see no reason you couldn't make something similar on the 450 pan.

I had one of those cb400/4s back in the day Tom - had forgotten how cool the original seat with the buttons around it looked. Looks like a good job your dad did.

Ah I know. I don't have any skill in the area really, but could farm out the upholstery bit easily enough. The things I suppose I'm worried about are whether it is possible to create a similarly stylish seat without having to butcher the 450 seat pan - or heaven forbid - start modifying frame loops and suchlike :(

I don't think you would have to cut up the pan but you will need to add foam and shape it then send it off to have it upholstered. Cover will be a little tricky to cover the hump.

Search giuliari. They made beautiful seats for cb750s and others. Import knock offs are out there, but they're made cheap to sell cheap.

35 euros including postage to my door - that IS cheap :eek:

I know the brackets are wrong for the 450K - but can't help wondering if it'd be worth buying one and rigging up some brackets to bolt it to the frame and keeping the original seat as a spare.

...used image search and found the original link to the bike:
the cb450 seat - Chin on the Tank ? Motorcycle stuff in Philadelphia.
Incredible - the very bike that was originally the intended recipient of the MegaCycle cams that LiamG6 ended up buying from him (Ed), and then Liam and I later traded sets of cams and those cams are now in my red 450! All the way from the States to Oz and back to the States. Check the comments at the end of this link

@alan

No need to mod a thing because Texavina sells these bolt on. They make them for a variety of Hondas, Kawasaki bikes, too. They also sell on Ebay. I personally have no experience with them but some members here purchased and despite being shipped from Vietnam, were good quality units. if you order, let us know here about your experience

Trying to talk myself out of this, but you're not helping guys.. :)

The Corbin seats I always knew were good but expensive - the Texavina ones are cheaper but are still going to come in about 300 euro once the taxman adds his 23% import levy :twisted:

I bought one very similar to that, and I can confirm that it is a piece of junk. Typical low bucks 'café racer / brat bike / garden ornament stuff.

I'm not going to use it. Current plan is to build my own, using an SL175 aftermarket seat cover, make my own base with suitable handcarved foam.

I have a import scrambler style seat for my cl350 project. They made it with a fiberglass copy of the original pan. It bolted right up, but seems pretty flimsy. To early to tell how durable the cover is. But if it rips out tears out right away, I won't be heartbroken. I'm not expecting it to be a show bike.

What don't I like ?

It's just cheap, less than 20 quid over here, and it shows. Flimsy plastic base, cheap vinyl with stitching that would let the rain through into the low density foam filling.

Looks the part in a photo, or an Ebay ad for a ' professionally built café racer', less so in the flesh.

Regarding the tank gap, seat isn't actually bolted to the bike, just placed there for photo. The stock seat latch mech got in the way of placing the seat closer to the tank.
