Majesty 320 Kronenberg

Daniel Kronenberg found the remainings of a Yamah TY 320 Majesty on a farm in the Kanton Bern (Berner Oberland), Switzerland.

As it was rusting around for many years, the farmer did not know, if this motorbike was still around somewhere in his shed. Dani called him after one week of first contact and the farmer said, he found something an rolled it out in front of the stable, to be collected. The next day, Dani arrived later in the evening, but nobody was around. On the mobile, the farmer told him to take it, otherwise he would dump it. As an honest man, Dani left some money in an envelop and loaded the Yamaha.

The project starts:

the shed found, a Harley bar? years of mud and dust
after first cleaning rust, rust, rust
end target Frame Number 81 0775
this number was found 35 years later at the Swiss Yamaha importer's archive
Hostettler Yamaha and confirmed by an Import Certificate

Now, for thoese who don't know Dani Kronenberg, here some links to his former procects:

So, there is not a lot of info about the Majesty.

 

yamahaty.com has a story:

At the end of 1978, Mick ANDREWS (MA) and John Edouard SHIRT (JES) produced the MAJESTY modifying the TY 175 AND 250 frames. Then from 1980, frames will be built by Don GODDEN. Many models will be produced in 125, 175, 200, 250 and 320 cm3 capacitys and also long or short frames (mini majesty 100 and 125 cc). The Majesty story will end with the arrival of the monoshock TY in 1984.

yamaha-majesty.com has parts. Steve Martin bought it from Greg Mawlaw and we ordered a big amount of new parts, highly recommendet, great service.

tytrials.co.uk has many Yami and other twinshock parts (Honda).

I found a price list in my old boxes. Christian Aeby, also a Yamaha Majesty owner and back in the 80ies as a Yamaha dealer involved in importing Majestys and himself competing in the Swiss top trials class, told us, that about 20 Majesty 320 were imported into Switzerland. Dani owns now one of those and the importer Hostettler Yamaha could today (2015) track the import document with his frame number.

It must be a 320cc Majesty Mark 2 built in 1982, as in 1983 the rear mudguard holder was cut and in autumn 1983 the TY mono arrived.

 

Here the restauration in process

many parts polished better than new
before after...Dani is a giftet polisher
Dani sourced a new piston in Germany from a DT 360 (Canadian  version) , 80mm first overbore sizem, the cylinder was fitted to the new bigger piston, 320cc looks all good
important measures for sourcing DT 360 pistons, found in Canada ebay
80mm diameter original, one overisze DT piston was then sourced and fitted here it needs some special skills (horrible for me)
the piston fitted, without the additional weight on the flywheel (no good idea, was added after first test) the internals of a Yami
electronic ignition a new engine side cover was made by Dani
as the side cover was badly damaged Dani just made a new one...
  side cover in black
all newly painted a Majesty 320 frame
 
Dani made himself a new alu bracket, made out of a alu block. The carbon holder is new 4RT  
the powder coated frame is back  from the paint shop,
 new tank and saddle from Steve Martin,
28mm fat bars fitted,
new hard rock pegs fitted, new side stand holder
progressing behind is the additional ring for the 320 flywheel weight

In many long winter nights, time passed and the TY 320 became born.

 

2016 February 27: The maiden run

many great details, unfortunateyl my cam ran out of battery... front brake cable has new routing
   
the side cover of the ignition is made by Dani out of a block of alu  
Dani and David are discussing WES exhaust with carbon cover

For this piece of art, Dani Kronenberg gets the crown

Krone = crown

 

Dani let me quickly try it: The Majesty runs quite nicely, the frame feels lighter and the back is more floating than the 1975 TY250 as a comparison.

The heavy ring was not fixed to the flywheel, as Dani wanted to try a more responsive modern engine, but it was too agressive, so next time, the additional weight should smooth it down for more torque. The big 320 engine needs it. I'm looking forward to the optimisation of this beautiful reborn Yamaha.
