Greetings from Barcelona! Seeking for advise :)

Hello everyone,

My name is Albert, I'm 29 years old, from Barcelona.

Although my professional background has nothing to do with mechanics, I'm a chemist, I've been fascinated by vintage machinery for as long as I can remember. Before I was old enough to drive, I was already collecting and running small live steam engines, and I've always been drawn to the engineering, craftsmanship and aesthetics of pre-war vehicles.

When I was 16 till 19, I spent a few summers working in England and, with almost my very first paycheck, I made what was either a brilliant or terrible decision depending on how you look at it, I bought a 1957 Austin A35 on eBay without even seeing it in person.

As many of you will already be guessing, reality turned out to be somewhat different from the advertisement. What followed was a six-year restoration project :roll:

Image Image Image

The original plan was to do the minimum necessary to get it on the road. Then I found some rust. Then some more rust. Then another component that "might as well be fixed while I'm here". Before long, the project had completely taken over.
In the end I restored virtually everything myself. Engine rebuild, gearbox work, brakes, suspension, electrics, bodywork, welding and fabrication. I started with very little practical experience and learned almost everything along the way. Looking back, I probably spent several times the value of the car in parts, tools and "while I'm at it" decisions, but I wouldn't change the experience for anything.

Image Image Image

One of the things that made that project possible was the Austin A30/A35 Owners Club forum. I'm a member there, and the knowledge, generosity and willingness to help from fellow enthusiasts was incredible. Whenever I got stuck, somebody had already faced the same problem twenty years earlier and was willing to share their experience.

That experience gave me a huge appreciation for British classic vehicle clubs and forums, and it's one of the reasons I'm introducing myself here. While restoring the Austin, I always had another interest in the background, specially vintage motorcycles, particularly British pre-war machines.
The problem was that I didn't have a motorcycle licence. Now I finally do :)

For years my dream vehicle was actually an Austin Seven. I still love them and may eventually own one someday. However, having already gone through one complete car restoration, I'm not quite ready to start another large-scale project. Also I'm not quite sure it could cope with nowadays traffic, which is one of the main reasons i went for an A35 instead.

A motorcycle seems like a more manageable undertaking in terms of space, complexity and logistics, while still offering everything I enjoy: mechanical understanding, historical engineering and hands-on maintenance. This is what has brought me to Ariel!
I've looked at BSA, Norton and several other brands, but I keep finding myself drawn back to Ariel. Part of it is undoubtedly the styling, but part of it is also the company's history.

Professionally, I work in innovation, helping organisations identify new opportunities, technologies and ways of thinking. Because of that, I've always been fascinated by companies that were willing to challenge established ideas and take engineering risks.
Perhaps this is an oversimplification, but when I read about Norton, much of the story revolves around racing success and competition heritage. Ariel seems to have built a reputation for engineering creativity and technical innovation, whether through adopting unconventional ideas, supporting ambitious designs, or simply being willing to do things differently, and that aspect resonates strongly with me.

At the moment I'm trying to understand which Ariel models would make the most sense for me, and I'd greatly appreciate guidance from those with more experience. My priorities are probably a little different from someone looking for a museum piece.

First, I'd like a motorcycle that can cope reasonably well with modern riding conditions. I don't intend to commute through Barcelona traffic, but I would like to enjoy secondary roads and longer touring rides. My father lives around 200 km from Barcelona in a mountainous area, and I'd love to be able to make journeys of that sort occasionally.

Second, reliability and robustness matter to me. As I've started researching different models, I've come across discussions about aluminium heads, model-specific weaknesses, durability differences and various engineering quirks. I'd be very interested to hear which pre-war Ariels are generally considered the most dependable and practical to own.

Third, and perhaps most importantly, parts availability.

One of the reasons Ariel appeals to me is that the owners' community appears to be active and organised, particularly regarding technical support and reproduction parts. That is a huge factor for me.

My experience with the Austin taught me that even when parts support is generally excellent, there are always a handful of obscure components that become incredibly difficult to find. Usually it isn't the major mechanical items that cause trouble, it's the small brackets, castings, fittings or model-specific pieces that suddenly become impossible to source.

Because of that, one of the things I'd really like to understand before buying is what those "unobtainable" Ariel parts are. Which components should I pay special attention to when inspecting a bike? Which missing or damaged parts should immediately raise a red flag?

I should also mention that, unlike when I restored the Austin, importing parts from the UK has become considerably more expensive and complicated since Brexit. During the Austin restoration I had pallets, crates and parcels arriving from Britain on a regular basis. Today the economics are quite different. That doesn't stop me buying a British motorcycle, but it does make me much more cautious about taking on a machine that will require extensive sourcing of hard-to-find components.

In many ways, I think I'm looking for the opposite of both extremes. I'm not searching for a museum-quality showpiece that I'm afraid to ride, but neither am I looking for a basket-case restoration project. Ideally, I'd love to find an older restoration or a well-maintained machine with honest patina and history behind it. A motorcycle that has already lived a life.

My philosophy with classics has always been to preserve originality wherever possible while making sensible improvements when reliability genuinely benefits from them. For example, on my Austin I fitted electronic ignition, not because I wanted to modernise the car, but because the original distributor components were beyond saving and the upgrade was visually almost indistinguishable while making the car significantly more dependable.

I take exactly the same approach with motorcycles. A few scratches, some age-related wear and the occasional rust spot don't bother me at all. In fact, I often prefer them. What matters to me is authenticity, mechanical integrity and the confidence to actually use the machine.

Another question I have concerns engine size.Many of the pre-war Ariels that interest me seem to be either 350cc or 500cc machines. My instinct currently leans towards the 500cc models, partly because of the hilly roads where my father lives and partly because I'd like the option of occasionally carrying a passenger. My partner enjoys motorcycles too, and while I appreciate that these machines were designed in a very different era, I'd be interested to hear real-world opinions from owners.

How significant is the difference between a 350 and a 500 in everyday use? Is the extra torque worthwhile for touring? Are there reliability, vibration or maintenance trade-offs between the two?

I also wonder how these motorcycles generally cope with modern ethanol-blended fuels, and whether overheating is something owners need to think about during long summer rides in warmer climates such as southern Europe.

At this stage, I'm still very much in the learning phase. Before buying anything, my intention is to spend a good amount of time reading, researching and understanding the different models properly. I've already started collecting a few books on British motorcycles and Ariel history, and I plan to spend quite a while learning before making any decisions.

So perhaps my final questions are these:

* Which pre-war Ariel models would you recommend for someone who intends to ride rather than simply display the bike?
* Which models have the best parts availability and club support?
* Which difficult-to-find components should I pay close attention to when inspecting a motorcycle?
* What are the most common mistakes first-time Ariel buyers make?
* Are there particular dealers, auctions, clubs or marketplaces that you would recommend?
* And finally, are there any "must-read" threads, articles or technical resources on this forum that every prospective Ariel owner should study before buying their first machine?

Please i don't expect to get answers to all of this questions in this post!! Its just a share of my thoughts, I would appreciate if you could point me out to some threads that can help me with any of the above.
I am in no hurry to buy. I'd rather spend six months learning and buy the right motorcycle than buy the wrong one next week.

Thank you for having me here and best regards,

Welcome !

* Any post 1927 single OHV and SV up to 1954 have the most smiles per miles, perhaps not the fancy early thirties 4 valve models and certainly not the Square Four, although they look as the proper posers bike and have a wonderfull sound, they are cumbersome and overweight to their frame.
(I will now be taken to a remote area and trampled to death by the SQ4 posse) :lol:
* Singles.
* All tin parts like mudguards, prewar center knob toolbox, prewar handlebar levers (solid) should be on the Ariel you want to buy.
replica's are made but stay away from Indian made -Death Wish- front forks.
* Not buying a Ariel sooner .
* Be a member of the AOMCC, and this forum should be a everyday event in your dairy.
* First decide on the model you want then read all you can find about it, the knowledgebase from the AOMCC is a good start.

Keep us informed !

Succes.

Hi thanks for the reply! I'm reading through some posts in this forum about the square four overheating and just basically eating pistons every few miles and I'm starting to get a bit scared :lol: :lol: :lol:

Well, to be honest, they are fine bikes and they do not (excessively) overheat or eat pistons, it just needs a dedicated owner .
Anyway, the best move to start with a Ariel is to buy one that has been restored or is in original and used state.
Starting with a restoration project is always going to cost more compared to a already restored one.
- I am just wondering why I wrote that, be there doing that......-

Don't buy a Worn to a frazzle, damaged or corroded Bike. It's a Buyers Market today. Take your time and buy well. A good petrol tank is a Must. At your (Tender) age and fitness you will be able to Kickstart a 500 OHV single. IF you learn how. The Magdyno MUST be good and unbutchered. I'd stick to rigid frame, iron Head and barrel with Tele Forks and a BAP box say 1950-51 VH model., The brakes are good enough and it's before BSA took over. Have you seen any Sanglass bikes in Spain?. Welcome to ARIEL. Nev

Hi, thanks for your message, I'll bear in mind. The 1950–51 VH you describe seems like a good compromise between the more vintage pre-war feel and a bike that can actually be ridden and maintained without too much hassle. However I must admit i still like more the earlier versions! Late 50s versions already start to feel a bit too modern for my taste. But 1950-51 seems a sweet spot.

About the gearbox, i'm reading in Draganfly and i got a bit confused, you mean the Burman heavyweight box of that pre-1952 type right? Rather than the lighter CP box, and the later GB

Regarding Sanglass, yeah, they were manufactured very close to Barcelona. The late 1960s and 1970s 400 cc models come up for sale from time to time here in Spain, but the very early 350 and 500 models seem much much rarer. As far as I understand, the first 350s and early 500s were produced in very small numbers compared with the later bikes, on the hundreds. They are interesting machines, I'm keeping an eye on older models but really impossible.

Montesa is also an interesting brand from Barcelona, it has its beginnings in 1945, however they made only very small engines (100 - 125cc) after spanish civil war and WWII, so they dont fit me for touring.

With Ariel,the Later 500 OHV SINGLE models fit the BAP and the CP are used in 35O's and are considerably lighter and could be used in a Trials bike. Till 1938 the Valves were not fully enclosed and lubricated. They are Much harder to get Heads for. A single Port Head is better and less cost for Pipes. The GB has always been harder to get NOS parts for. It would be cheaper to BUY a Good solid bike as older folks are finding difficulty Starting them and there are some real bargains to be had and restoration costs are Increasing while resale Prices are dropping for this kind of bike at the Moment. Chroming is harder to get done these days. A 1951 bike is 75 years old, Nev
