Built in England from 1911 to 1961, the bicycle company was started by the Parkes family and later merged with the Raleigh group. Production of motorcycles began with Villiers engined
346cc singles, and then after WWI utilised Vitesse rotary-valve twostrokes and Villiers engines, as well as larger JAP and Blackburne units. Motorcycle production lapsed between about 1936
and 1945, after which 98cc to 225cc Villiers-powered machines were produced, including the Sunwasp scooter with a 173cc engine which propelled it to 50 mph.
by Roger Yates 
The brand has its origins in James Parkes & Son, a brass foundry making, amongst other things, incandescent lamps - hence the eventual "SUN" brand
name. When cycles became popular they diversified into cycle fittings and in 1907 they formed a limited liability company as "The Sun Cycle and Fittings Company". By that time they were already producing the Sun Spider bicycle (a penny
farthing) and they continued to produce bicycles alongside the production of complete motorcycles, which started in 1911/12 using initially Villiers IOE engines before settling on Precision. Sun were also prolific manufacturers of parts for other UK and overseas motorcycle
companies, the latter of which would re-brand Sun products with a local name. Examples of this are: -
1913 saw the introduction of the first Villiers powered 2 stroke model, a relationship that continued through to the demise in 1959, but 4 stroke JAP and (briefly) Blackburne engines were also used by Sun well into the 1930s.
If that were the whole story Sun would be just another brand of motorcycle that somehow managed to survive throughout the "Golden Age" in spite of the recession, but alongside the proprietary engine range they developed the VTS engine following the acquisition of the Valveless Two-stroke Company. These were advanced single cylinder 2 stroke engines of 269cc with an excellent performance.
First introduced in 1916 alongside the Villiers and JAP models, initially these VTS engine machines were largely exported to such places as Portugal and Australia until war work ended production at the end of the following year.
Production of the engine recommenced in 1920 with a changed layout and a model name change from Sun VTS to Sun Vitesse. The previously vertical engine was inclined forwards, and although the regulation flat tank frame initially remained the same, that too soon changed with a more sporting triangulated shape taking over. This redesign coincided with the introduction of the an even more advanced 247cc Rotary Valve sports version of the Vitesse of which two competed in the 1921 Tourist Trophy on the Isle of Man, doing very well with a 9th and 10th place in the Junior (350cc) event. This encouraged an entry in the new 250cc "Lightweight" class in 1922 but the over-lightening of engine components gave rise to excessive vibration, which caused the fuel lines to fracture. Nevertheless Gus Khun and L J Lord finished in 12th and 13th places after wrapping handkerchiefs around the fuel pipes to staunch the leaking. This lack of success ended Sun's involvement in racing but the models continued and a rotary valve Vitesse lapped Brooklands at over 70 mph in the hands of Kaye Don.
The brand name was eventually acquired by Raleigh industries, who used the Sun name for their "Sun Wasp" scooter during 1960/61, but that was just a post-script to nearly 50 years of successful motorcycle production. Although this was largely centred on utility 2 strokes, it must be acknowledged that the Sun Cycle and Fittings Company always produced machines with their own distinctive styling.

Hello, I have a Villiers engined motorcycle which I believe is a Sun 197cc, the engine has 417D stamped on it and the frame number under the seat is RMC 942 H can you confirm what it is from these numbers? I have attached a photo of the bike as I got it and photos of the frame and engine number. Many thanks, Alistair.

1931 98cc Sun Tourer
I wish to sell the SUN, it is unrestored , the 98cc Villiers engine runs and the Albion gear box works. Please see attached photo of the bike, as I said in my previous email it is unrestored, the handle bars do not look original apart from that I think it is all as built.
I bought the bike on 06/10/90 27 years ago it has 4 previous owners all local to me in the old buff log book which will come with the bike , I have the current V5C registration certificate ,
I had a MOT on the bike in Dec 2015 to allow me to put the original reg. number on retention, the bike now has aged related number YXG 278. I will sell the bike with or without its original reg. number OD228. I have attached a copy of the MOT cert.
The bike starts OK smokes a bit, has good brakes. That's about all I can think of.

In answer to a question posted under Villiers
Hi again, Sue A,
The Sun Cycle & Fittings Co of your home town Birmingham, were a major supplier of frame components to the motorcycle trade including Australia from 1911. They supplied the trade for many years finally fading away in the late 1950's. Amongst others they supplied Waratah which is why the Waratah looks familiar. Sun transfers are available from the English VMCC.

Sun Overlander ?
Hi , I had a Sun with the Villiers 2T in the mid 60's ( Edinburgh).I was great bike but my ignorance of the correct 2 stroke mixture meant I always needed a plug spanner to keep the plugs clean . The leading link front forks were a bit soft for road riding and the brakes were average but I guess par for the time.I could not quite get the "ton" out of it . 95MPH was the max before a plug would foul.It certainly beat my mates Triumph Tiger Cub!
Attached is the only photo I have so you have to put up with the schoolboy perched on it.
I hope this is of interest.

Many thanks for your prompt and much appreciated response. Please find attached a photo as requested. From a classic novuce stance I think the bike may be a Sun, but I cannot be sure from friends / our local DVLA records, and of course Villiers made engines for many manufacturers! Hope this helps, and thanks in anticipation.

Jim Griffins Mystery Villiers
Jim is quite right. His bike is a 1956 Sun powered with a 98cc 4F Villiers engine. Both frame and engine numbers are correct for that year.
Cheers guys......its nice to right for once!.......which sickens the wife big time!...now on to the next hurdle....If you guys are familiar with registering such a machine for the roads (I am told by DVLA I need to join a recognised Vehicle Owners Club to verify the authenticity of bike
identification.....but the list of such clubs thtey sent me does not have a Sun club) I would be very grateful if you could tell me where to go next and / or if the detailed info which got you to your I.D. on the bike would suffice. Sorry to be a pain.....I can send an A4 SAE if that helps to forward info.
Thanks again in anticipation.

Sun Wasp 175cc Villiers 1964?
I own a Sun Wasp Scooter in Cream and red and am looking to sell it to a great home. It has a 175 Villiers engine with 12volt system and an electric start.
Unfortunately I do not have any photographs currently as I am in California and the bike is in the UK at my fathers house. I will email my Dad and ask him to take some photographs of it, and email them to you, if you would like. The bike is in very good condition although it has not been run for probably 10 years. I know that it has around 3500 miles from new and I know the history. My grandmother was going to be a distributor for these bike and so this was her demo model. I was around 14 years old when I got it and stripped, painted and rebuilt it. My father owned a garage business at the time and so it was my project! That was back in 1978 and I have owned it ever since. I know that I have the original 'fold out' log book in the UK.
If you would like any additional information please contact me. I have no idea what it is worth so some guidance on this would be welcome also.
regards, Alen Cooper

I have a motorcycle that was used in Canada by a constable in the 1920's-30's. It has a Villiers V engine in it, serial number 8011579. It is called the "sun". I would like to get some more information on it. It was my grandfather's. You have to pedal it to start it.
I can send you a picture if that would help.
Thank you for your consideration.
