U T KTN125169

Nice spring day off on a ride with the TWN ‘cornet’ magazine cover from May 1956

In 1984 a bought a Claude Rye TWN ‘Cornet’ at the time i didn’t know about the ‘Cornet was a split single, I restored the’Cornet’ pictures below,I had the bike in use for about 2 years but sold it on to make way for other bikes and restorations. It’s now 2018 and after almost 35 years i have gone full circle and now own 2 ‘Cornets’ all in parts some bits missing which i hope to put back together at some time. I have also started a ‘CORNET REGISTER’  some of which are still up and running others that are in the ‘Cornet’ dead park. So i would like to hear from any ex owners/ present day owners about the history,memories or any experiance with ‘Cornets’ UK or worldwide

PS if from the UK reg numbers frame/engines would be great

‘CORNET SPARES WANTED’      Thank you.

The ‘Cornet’ was a factory model reduced to 175cc  ridden by Herr Hans Hutter in 1955 Hans had to return the bike to the Triumph factory in 1956 they made very few machines ! so even pictures are a rare item.


Hans ready for the Start.

426 is a 1954 ‘Cornet’ and 432 is a 1957 ‘Cornet.


Motorcycling did a road test on the kickstart version in february 1955 but also did this one page test of the electric start ‘Cornet’ in October 1957


Adverts showing  cornets for sale at  lowering prices! they finally reached £129 10s 6D in direct competition with there much hated rivals Pride and Clarke selling the DKW RT200VS.

Also for £2 10s 6d (£2 52 and a half pence) you could have your ‘Cornet’ delivered to your nearest rail station result is ‘Cornets’ seem to be spread to all corners of the country!!.

Before Claude Rye sold the ‘Cornet’ it was available from D.Salem ltd in Manchester and it would have been the kick start version.


A few years ago, i was talking to a man who turned out to be a ex Claude Rye mechanic he told me that the ‘Cornet’s all sold about 300 in total and they were a good commuter bike well built machines, But they had a achilles heel in regards to the pistons and barrel wear! if they were used in high speed runs  i think thrashed is another word!!  problems with the exhaust piston would occur ie the cool induction piston kept the much hotter exhaust piston going in not ideal conditions so wear would take place around the ring area and on the barrel .The barrels are chrome plated and repairs are expensive, they can be repaired by POETON or NICKOSIL, and around £250 per barrel plus your pistons at £100 each so beware. below is a all to common sight when stripping down a Cornet engine…

cornet piston damage

sad sight of a ‘Cornet engine damage on piston skirts and rings they are ready for the bin!!

Cornet barrells

The barrels don’t look too bad! but any cracks or chips in the chrome bore is a re-plating job!!

A firm who can replate the bores are..
