SUN Cycles

Re: Sun motorcycles

Sun Motorcycles, like so many other MC firms, came out of older, bicycle, firms. The first Sun Motorcycle appeared in 1911 and continued in manufacture until 1933. After WWII with the dearth of cheap transport, Sun started again with a 'moped'. Like most of these, flimsy tin pressings housed a Villiers engine. In 1948 a lightweight motorcycle appeared, known as the Challenger. Sun produced many variants in the 50's, the 99cc Hornet, 224cc Cyclone and 249cc Wasp twin, there were competition variants too. In 1957, they jumped on the scooter craze with the 99cc Geni.
By 1960 however, like so many B'ham MC firms, Sun having been owned by one family since the start, they decided to retire. All manufacturing rights were sold to Raleigh, and any post 60 Bicycles came from Worksop.
Does that help ?
 
Are there any other Sun Cyclone owners out there?
I have one manufactured in 1955 and first registered in 1956. I had this restored in 1999 and to the best of all the info I have tracked down so far, she looks pretty original. She does not have the optional chrome tank plates but does have what appears to be Challenger MKIV brass tank badges. May of the parts are pattern or after-market now but I would love to hear from anyone with any more info on these machines. Willing to share.
 
Apologies to anybody clicking on my Flickr links in my old posts above. They are all dead since I closed that account.
I will edit them out if I can, since clicking on dead links is quite annoying I know very well.
Most of my stuff is now being transferred to my own site here:
https://www.bicyclz.com/

There are a few Birmingham bikes on there, plus some of Leonard Gundles great carrier bikes, and Royal Enfields, Rudge, etc.
More to be added as I get time.

John.
 
Re: Sun motorcycles

I have just coming into a Sun Challenger 197cc original paint and in many pieces. I will be bringing it back to life and wondered if there were others out there who have recently done the same. Andrew
 
Re: Sun motorcycles

Hi Andrew we also have a 1954 challenger waiting to go back together. What year is yours?
Regards Bud.

Mine was built in 1956 and registered in 1957. Same as me.

Same as me. We put it all together with a friend when I was 16 and we found it in a friends shed. Still original paint mostly and the engine turns over.

What shape is yours in?

Re: Sun motorcycles

All repainted and engine restored waiting to be put together. Working on a 122cc at the moment so it will have to wait.
Yours must be a challenger mark IV with a Villiers 8E engine and a frame prefix of VMC.
Keep in touch on the progress and post a photo when finished and I will do the same.
Regards Bud.
 
Can see there are no replies here for a few years now!

Does anyone here have a 197cc plunger? I'd like to connect with you if so.
