Vincent Series C Comet facts
1. The Vincent C Comet was produced in 1948 and priced at approximately £240 (including purchase tax).
2. Comets, like many other Vincents were fitted with a Feridax dual seat.
3. Many riders consider the Comets to have superior handling to the big twins citing high-speed "jittering" problems with the Rapides and Shadows. Conversely, other riders claim the opposite, which probably simply makes it a case of different strokes for different (sized) folks.
4. The Comet has twin (linked) front brakes and twin (linked) rear. The company favoured control rods where possible rather than cables to preclude rider maintenance neglect.
5. The 998cc V-twin Vincents have an unusual clutch that operates partly like a more conventional multi-plate unit, and partly like a drum brake (with an inherent self-servo function). It was developed specifically to handle the extra power of the larger capacity bikes. But the Vincent Comet, having a lower power output, has a fairly typical multiplate clutch unit.
6. Prior to 1950, Vincent motorcycles were called "Vincent HRD". The initials "HRD" referred to Howard Raymond Davies, a successful and very popular motorcycle celebrity racer and ex-WW1 pilot who started his own company in 1924 (to 1928). Phil Vincent, aged just 19, bought the HRD name and rights and used the "HRD" initials until the firm became more active in the US market and needed to avoid public confusion between their product and the large V-twins of Harley-Davidson (HD). Post-1950, Vincent motorcycles became simply "Vincent".

"I bought my 499cc Vincent Comet in 1970 and paid around £65. It was a local bike that belonged to a friend who had had a sidecar on it and had toured heavily. The name Vincent, naturally enough, carries a lot of weight, and like a lot of people Iíve always been interested in the company, which was very local to me. But what I was really had in mind was putting a big Vincent V-twin engine into a Comet and I spent the next 38 years waiting for one to come up at the right price at the right time.
"Converting a Comet to Shadow or Rapide specification isnít hard. Just a little expensive. I recently missed out on an engine that would have done the job. The engine was priced at just £4000ówhich is a bargain. But for various reasons it didnít happen.
"You can now buy brand new big twin Vincent engines for around £10,000. But Iím still looking out for a genuine old engine at the right price.
"Of course, if you convert a single-cylinder Vincent Comet to a big twin, youíre not going to get top money for it. It wouldnít be a genuine Shadow or Rapide, and any serious Vincent enthusiast would quickly spot that and wouldnít be very impressed. But if you did the modification, youíd still have the big twin riding experience, and itís the riding that interests me mostly.
"My bike, incidentally, is 1950 Vincent ďCĒ Comet
(3,791 produced). The first Vincent Comets were built in 1935 (to 1939; announced in 1934). That was the ďAĒ Comet (prototype). The short-lived ďBĒ Comet was developed from that, and the C Comet came along in 1948 and was built until 1954.
"There was a Series D Comet made for that same year, but as far as I know it didnít go into production.
"Iíve ridden around 165,000 miles on my Comet, which isnít bad mileage. But itís nothing compared to some Vincent riders who have covered 500,000 miles, or more.
"Vincents are a very different riding experience. You tend to sit on top rather than ďinĒ them. Youíre almost perched up there. Itís not a bad position. Just different. I used to ride a lot more than I do today. Two hundred miles a day is plenty now. But I have done mileages as high a 1700 in a single week.
"One of my favourite riding events is the Irish Munster Rally. I've done that 14 times; 13 times on my Vincent, and once on my VH Ariel. For over 35 years, the event has been organised by the Munster Motor Cycle and Car Club and is currently staged around the 4-star Kenmare Bay Hotel in the Killarney/County Kerry region. Itís not one of the better known rallies, but itís one of the best for great scenery and great riding.
"The event is currently co-supported by Murphys, the brewersówho will probably in turn be co-supported by the participants.
"Generally, you arrive over a weekend in August. Monday night begins with a social get together. The riding itself takes place the following morning and continues on and off until Friday. Depending on the power and specifications of the bike youíre riding, you set your own average speed of either 20mph, or 24mph. Which doesnít seem like much, but some of the roads are pretty small and tight, and average speeds are often misleading. In fact some of the riding is pretty much off-road; a bit like the lowlands of Scotland. But there are stretches where you can get the speed up a little.
"Every year the route varies.
"There have been a couple of accidents. The year before last, for instance, an Irish lad came off his Norton and wrecked the forks. And I remember a rider on a BMW who was hit by a tractor-trailer or something and lost one of the cylinder barrels. Apparently, BMW cylinders come off a lot easier than you might think.
"But no one, as far as I can remember, has been seriously injured. Itís much more relaxed than that.
"The upper cut-off year for bikes entering the event is 1961, by the way. Thereís no lower limit.
"The way it works is this; you establish your route in the morning (after a full Irish breakfast) and ride around 70 miles. Then itís time for lunch. Thereís another 70 miles or so in the afternoon, all of this passing through 3 checkpoints. Itís not a race, but there are penalties and awards. Around 160 bikes or more usually attend.
"You get to meet interesting riders from all over the world. For example, the oldest machine last year was a 1907 German Triumph with a young German girl on it. There also were a couple of Japanese guys last year dressed like Kamakazi pilots. One of them commented that he particularly likes British bikes because they break down a lot - which, I suppose, makes them all the more interesting.
"Another Japanese guy was riding a Sunbeam which had a magneto problem that they couldnít sort out locally. So they put the bike in a van or something and took it all the way to Dublin where it was fixed overnight and ready to ride the following day.
"Thatís the kind of spirit that makes it worth riding the event each year.
"You do have to put up with some modern riders getting in the way, but just a few. You never, or hardly ever, see any police.
"Jeff Smith rides regularly on (as far as I know) a BSA DB34 Gold Star outfit owned by Dave Bickersówho usually also comes along and rides a Matchless G80CS Steib outfit.
"The worst weather we had was 4 days of gales and rain, and the best was 4 days of non-stop sunshine. In Southern Ireland, with the Atlantic weather just over your shoulder, you never know what to expect, even in August.
"On the last night, incidentally, there's another big dinner, and that's that for another year.
"I met the now legendary Bud Ekins on the Munster Rally a few times. But the first time I met him (briefly) was back in the late 1950s when he was riding a Matchless in an ISDT event. When I met him again in Ireland about 10 years ago, I got to know him a little better.
"Bud was a bit of a whisky and fags man; a great big bloke and typically West Coast American. As most people know, he was heavily into desert racing, and had ridden for Matchless and Triumph. When he packed that up, he started doing stunts for filmsóboth cars and bikesóand later became famous for doing ďSteve McQueenísĒ bike jump in The Great Escape.
"Bud always had lots to say about the American bike scene and was interesting to listen to. He generally came over with a few mates from the United States and was riding Matchless bikes mostly. I think he kept a machine or two in the UK or Ireland for convenience.
"As far as I can recall, Eric Cheney built Bud a bike a few years ago. Budís health was declining, and the Cheney bike was a very lightweight machine with a small unit Triumph engine. Bud dropped it on one occasion and when I spoke to him afterwards to check if he was alright, he said ďwell, my heartís still going at least, so I suppose Iím still alive.Ē
"The last time I saw Bud was in 2006. He didnít look too well at all, which was particularly sad because, as I said, he was such a big bloke and now didnít look so big. And when I asked about him in 2007, one of his friends said that ďheís a poor old thingĒ now, and of course he was gone the following year.
"Anyway, the Vincent Comet was almost always my bike for the Munster Rally, and has been pretty reliable. Itís more or less original except for a few points worth mentioning. It was designed to run with a magneto (itís actually had three mags on it), but some years ago I converted it to coil ignition.
"Itís also running an alternator taken from a Citroen 2CV. The alternator is driven by a vee-belt. The belt acts as a kind of shock absorber. The good thing about the 2CV alternator is that it doesnít have a rectifier built into it, which is often the part that fails on the road. For rectification, I use a tiny Lucas unit that sits underneath and is easy to get at.
"The alternator runs at engine speed and replaces the original 50-watt dynamo. It puts out around 120-watts. This 12-volts system is far more reliable than the original 6-volts system. I paid around £10 for the alternator, £12 for the regulator. And another £12 for the extra bits and bobs. I also use a contact breaker from an early BSA C11. I think a more modern alternator is an essential upgrade for the standard Vincent charging system if you plan to do any serious riding.
"The carb is a 276 Amal, which was how it left the Stevenage factory. I suppose I could upgrade that too, but Iím happy with the 276. The bike has also got the original Vincent dampers.
"Working on the Comet is easy, and you donít need too many tools; just a few pullers which you can get almost anywhere. In fact, itís just had a new big end on it that was sorted out by Bob Culver, the Vincent specialist in Letchworth, Herts.
"The Comet engine, like all Vincent engines, can be dropped out of the bottom of the bike. You simply prop up the engine at the rear (with a some blocks of wood or something) and use the two side stands at the front (one on each side) to hold up the other end. After releasing the petrol tank, a few oil pipes and some electrical connections, itís just a matter of taking out a handful of engine bolts. Then youíve can wheel the bike away and start on the engine. Couldnít be simpler really.
"And these are tough engines anyway. Phil Vincent and Phil Irving built them well and didnít compromise on much.
"On the road, the handling is good, if not remarkable. Thereís not a lot of power mind. Vincent Comets put out only around 28bhp when new, and the top speed was no more than 90mph or so. But itís all usable power, so you can push it hard and get some real riding pleasure from it.
"Braking is brilliant, both front and back. Vincents of that era used twin drums at the front, and because theyíre twin, they tend to stay cooler than a single larger unit, and so don't fade easily. I recently had them serviced by the aforementioned Bob Culver, and you can pretty much lock them up if you want too. But theyíre not hard and aggressive like, for instance, modern brakes. Theyíve still got plenty of feel.
"Bob bonded new linings to the shoes, then put them on the back plate and fixed that to his lathe. Then he skimmed the shoes. That makes a lot of difference and gives you a smooth action and progressive braking.
"I used to be an electrician and rode the bike to work every day for years. Also, Iíve been in quite a few VMCC runs and touring rides with friends, etc.
"Itís always been pretty reliable. Iím not sure about its current value, but it must be somewhere between £6000 and £10,000. I couldnít be more accurate than that because I just havenít considered selling it.
"People often say, derisively, that a Vincent Comet single is just half a Rapide twin. Which is true. But a Comet is arguably also half the trouble. I think itís an underrated bike, and Iím very happy with it."
