Triumph CornetCornet Claude Rye

This a advert from July 1957’Motorcycle’ about this time the German motorcycle industrie was on decline with bikes not selling in the showrooms.Claude Rye obtained a batch of 200 ‘Cornets’ and sold them at the price seen in the advert.In the spring of 1958 they reduced the price down to £129 10s 6d to compete with there arch rivals  PRIDE & CLARKE selling the DKW RT200VS at the same price.Both bikes were quality machines selling at about £25 cheaper than a James or Francis Barnet.For a another £2 10s 6d you could have the ‘Cornet’ crated up and sent to your nearest railway station.Because of this’Cornets’ seem to scattered all over the country not just around the London area.Claude Rye salesrooms are now the Fulham football Club salesrooms.

A few years ago ,i had the good fortune to meet a ex Claude Rye mechanic who told me the little’ Cornets ‘sold in reasonable numbers and were in general good reliable bikes , but there achilles heel was if ridden hard they tended to nip up(seizure) probobly due to the piston on the induction side running cooler and keeping the exhaust piston going when conditions were not ideal for it!As a result ring,piston and worst of all barrel wear would result.The problem with the barrels are they are chrome plated so cannot be rebored.Most of the ‘Cornet’ engines i have seen all show signs of wear in that area.   Below is another advert from Claude Rye,plus a Comerfords advert for the Adler ‘Favorit’ but the private one is bit of a find!!! I thought the 250 BDG or in this case the SL version were never imported to the UK.The advert proves me wrong a new 250BDG SL for sale I wonder what happen to it???

By December 1958 with sales of Pride and Clarke’s DKW RT 200VS selling well,Claude Rye lowered the price of the ‘Cornet’to the same as the DKW.
