Brevettato Bars for Jota

I don't know Joe, these are just some of the many imponderables that seem to between you and the handlebars of your dreams... I suspect this one's going to be a long restoration! :D

Hi Joe

the Raask bars seem to go for about 100 GBP or less, at least when I last checked some time ago.

original Laverda Jota bars are now more thna 30 years old, so depends on condition, but a nice rechromed straight set might fetch 250- 300 GBP or more depending on the bidders.

the big black BREVETTATO marked on the bars offered by GiovanniMoto sure doesn't look original, and as they are being sold as new, I would suspect they are pattern made bars, maybe even RAASK but marked up in price considerably. I doubt very much they are new old stock. Best would to ask GiovanniMoto as to the manufacturer, especially if they are RAASK you might want to source them somewhere cheaper, 142 GBP feels a little stiffly priced to me, but then I have been accused of being cheap occassionally, and it was competing eBayers who drove the price that high....... :o

okay here they are. i am not impressed. shitty welding and not properly polished around the welds. otherwise the chrome looks good. could have been nice. classic case of spoiling the ship for a ha'pworth of tar.

Hi Henry

you get what you pay for, there is a reason they are a third the price of a nice original. Having said that, they do the job, are brand new, have fresh chrome,and very few people will know they are not the real thing, so a worthwhile product.

aren't the handle bar end pipes also significantly longer than an original, more room for grips/controls/etc, but a wider bar than an original?
 
I also heard that the centre section is a little shorter than the real thing. But remember we're talking about handmade Italian stuff here, I'd be extremely surprised if all the "Brevettato" bars have exactly the same dimensions. They must have had alignment fixtures at whichever factory made them but there had to be variability in batches of tubing, cutoff lengths etc.

point taken, paul. they are, at least, functional and as you say most people won't even see it. quite frankly, since they aren't the real thing, i might polish the chrome off and paint them black. then everyone will ask me where i got black ones from :LOL:

as for dimensions - centre section measured through the centre of the tubing 276mm nominal
                         bend, front to rear -                                                     78mm nominal
                         handlebar inc. the adjuster                                           300mm - 270mm to the weld

i haven't got the originals where i can measure them, so how does that compare?

sitting on my classroom table they do look quite longish!
 
Having been forced down twice , once by a cage and once by an oil spill in a fast curve I aquired 2 "Brevettato" handlebars to my original damaged one.

Center section on 2 is/was 276mm nominal as well, the third is 288mm nominal (stamped Brevettato)
Bends are in about 78mm on all 6
Handlebars are about 243mm overall length on the 4 I have with the slanted screw on end and 260mm on the single handlebar that I have without a slanted end (Raask?, shitty chrome, not as heavy as the rest)

Gerald
 
My bars are stamped Brevettato and have the same dimensions as yours (Gerald) - ie. 288mm centre bar, 243mm handlebar ends. The welding is smooth as in Stefan's photo.

On further inspection (beyond original post) it does appear that the machined [adjustment] ridges on the end of the joint pieces (ie. the pieces which fit between centre bar and handlebar ends, shown in the centre of Stefan's photo) are a couple of degrees out with one another at the handlebar end.

This could have been that one was clamped badly when machined or it could be that one has been replaced from a different batch. I'll keep a look out for a spare joint (which may be a closer match to one or the other), although they are much higher than the old fork mounted clip-ons so they're on the bike as is for now..

i had a set of those Raask bars, a while ago.  ended up chucking them in the bin.
the intermediate L angle bit that the cap screws bolt into was a brass or bronze.
one day i leant on the end of the bar and pulled the cap screw straight out of the tapped thread !!
maybe a bloke is not suppose to lean on 'em that much, but we have some rather large craters in our roads down under.
fortunately i wasn't riding Miss J at the time.
just my thoughts, and hadn't noticed anyone talk about the 'cheap' brass bits.
