I've got a carbed Fazer 1000, which I love, but whose luggage-carrying capacity is limited. I don't want to encumber it with a huge tank bag and panniers, and have seen a small single-wheel trailer that attaches via stub axles in either end of the rear wheel spindle. I understand that this would increase the unsprung mass of the rear wheel, but am told by the maker that any reduction in suspension compliance is more than compensated by the improvement in handling over a fully-laden solo bike. Any useful comments would be appreciated (apart from the obvious, "get a Gold Wing"!).

I've never ridden a bike with a trailer but I can see the appeal. Performance in a straight line will be affected more than carrying the luggage in panniers etc as the trailer will weigh more, and I presume the rate at which you can lean the bike is affected with one-wheel trailers that lean with the bike, but not with non-leaning two-wheel ones.

You'd certainly get more unsprung weight using the arrangement you describe, but the magnitude of the effect is hard to guess.

None of which is very helpful, sorry!

Anyone else have experience?

Hey Wobbly, good for you. I take my hat off

Hey Wobbly, good for you. I take my hat off to anyone prepared to do the unconventional. Firstly let me say that I have never ridden with a trailer, but I was involved in the original legislation in the 1980s that made it possible and I have spoken to many who have and they are universally happy with their purchases. I was interested to see that at the Bike Show the 'wide white' (as I call it) is still for sale, from Squire, as it has been continuously since the start. To me it still looks just as ugly, but it clearly has a good following, proving that the product is well tried, tested and it works.

Leaning trailers clearly look a million times better and I have seen colour matched ones on sports bikes, one even stacked out in wine rack format for the Beaujolais Run! When talking to the owners, they claim that it makes very little difference to the handling and even the performance. The balance is of course critical, but with a single wheel trailer, even acceleration does not seem to be noticeably affected because it is totally in the slipstream of the bike. Apparently the only real worry is hard deceleration into corners, when it tries to push you straight on more that you expect, when your aspect changes as you are hard on the brakes. Obviously this would only apply when really wringing it anyway.

In respect of balance, I gather that the trim makes a huge difference, so loading is a skilled art to ensure that just the right amount of weight is bearing on the tow bar. Clearly also the position of the tow bar is critical and this is in my view the main disadvantage, i.e. the tow bar and how you mount it. I have not yet seen a mounting system that does not involve vast amounts of angle iron coming down at a strange angle backwards. On a Gold Wing it doesn't matter because you just add it to all the other angle iron (Sorry to any wingers, but it has to be said), but on a normal bike it does spoil the appearance and look strange.

So if you can find the right technical solution that does not make the bike look awful, then go for it.

Sorry that this is such a long post, but just to end with a nice trailer story. One of the original motorcyclists who worked on the legislation had a prototype of the wide white out on test about a week after it became legal. He was doing 90 mph on the M6 and was stopped by the police. The officer started on at him about how using a trailer was illegal and thought he was being cheeky when he started quoting the construction and use regs, so issued a notice of prosecution for using a trailer. He never did get done for speeding and of course the notice that was issued was invalid!

I actually have a bike with a trailer, though

I actually have a bike with a trailer, though not quite in the same league as you are talking about. The single wheeled trailer for bikes has been around for donkey's years over here in the Czech Republic or indeed Czechoslovakia as it was when they all kicked off. The local offering is called a PAV and is a simple enough idea that has a two pin hinge arrangement at 90 degrees to each other allowing the bike to lean and everything go up and down as required. Mine is hooked on to the back of a 1974 ex Czech military CZ175 cc two stroke. This is the bit where the relevance to a Fazer 1000 gets a bit hazy. I was warned that they were horrible things to ride before I tried it but I found that advice to be complete nonsense when I took it for it's first test ride. I was bumbling through the village with it behind me and I basically couldn't notice it was there. "Utter crap advice" I was thinking as I headed out of the village to the country roads and took it above 60km/h. It was at this point that I nearly kacked myself realising very quickly what people were talking about. It went into a horrible fish tail pretty damn quickly and that in turn had me weaving about all over the place and very rapidly on a collision course with some local tree like items. I managed to stop in time, and my life flashed before my eyes it had been that close. Mind you the boredom of that also nearly killed me!

Anyway the secret is to make sure that there is enough ballast in it to stop it wandering or ride below 60km/h. Now that I know these things I think it is brilliant and very interestingly, on top of the PAV there is a rack which is exactly the right size to take a box of beer. Coincidence? In this country I think not.

OK so that is my experience and I am sure it is not that relevant as no doubt the modern items will be a whole lot more sophisticated, just as is the bike you are talking about.

Thanks for your input gents. It's a real

Thanks for your input gents. It's a real treat to be thought of as unconventional rather than eccentric! I was a bit shocked by the vehemence of my mates' negative reactions when I first floated the idea, but then they also threw up their arms when I revealed that I had had the Fazer's tank extended to give me a 300-mile range (yet they're the ones that are constantly watching their fuel gauges on long foreign jaunts!).

Anyway, I'm encouraged that, based on what I've heard so far, I would be no more likely to end up in a ditch hauling a trailer than I would, for example, piloting a sidecar. I take your point about the extra braking effort required JD, but thankfully the Fazer's anchors are pretty good and I only weigh 9 stone!

The trailer I've seen comes with over-voluminous GRP bodywork, which also makes it quite expensive, so I'm wondering about buying just the chassis and fitting hard cases. I've just discovered that Givi make some for the Segway 'Personal Transporter' gizmo, whose bracketry clamps to a horizontal surface.

If these links work then you'll be able to see the what I mean here:

Shuggiemac, hadn't seen your post when I sent

Shuggiemac, hadn't seen your post when I sent mine - had me in fits! Don't think I'll be able to keep the Fazer below 60km/h so will have to take plenty of that liquid ballast that you mentioned when going to foreign race meets. The rides home could be interesting...

Wobbly - sorry can't bring myself to call you

Wobbly - sorry can't bring myself to call you Mr Wobbly as that just throws up all sorts of mental images that I really don't want!

I think that my experiences will be fairly irrelevant to what you are considering, so I added them only as a point of reference. The PAV is actually quite useful and on the upside when it is loaded the bike struggles to reach 60km/h a fair amount of the time.

At the Prague show last year there was firm displaying some very smart looking trailers hooked up to the likes of GSX-R's etc with flowing body work etc that kind of followed the lines of the bike. They were pretty long items if my memory serves me well and I did wonder if you would need to pay extra for it on the ferry.

If you take a look at this link then you can see some pictures of the PAV in various guises

Saw a group of Gold Wings quite a while back

Saw a group of Gold Wings quite a while back that had trailers. Now these weren't single wheel trailers so not entirely relevant, but something puzzled me and I imagine it would be even more true with single wheel trailers. The law (on cars don't know for bikes) requires unbraked trailers to have an additional attachment. This chain or cable keeps you together if the tow ball jumps off. Now several of these wings had chains fitted. Maybe I've not appreciated the scenario properly. Something in my head says I'd much prefer to explain the carnage caused by my trailer to plod than have a partially attached trailer re visit the rear of my bike???

If I had to attach a trailer to my bike with a chain I think I'd make it a very weak chain...
