It seems it's about time I fended off Arthur Middletons attempts to 'correct' my comments on the limitations of low CG motorcycle designs.

I beleive the original article spoke for itself if properly read and understood, but some have asked for a clarification upon Arthurs comments - so here it is.

Can anyone tell me who makes hard panniers for a 400 Burgervan

I'm having a hard time trying to figure out this site. Is there a page like a forum where a message is sent and others can reply to. Does my blog go out to everybody or only people who want to see my blog. How can I upload a picture of a FF project.

I'm passionate about having a choice in everything and that includes bike safety. I bought a BMW C1 4 years ago and I still think it is a brilliant concept and a really enjoyable ride round town. I needed to travel further two years ago so bought a Honda Silverwing scooter and I'd love to see Honda bring out one with a safety cell like the C1. The BMW C1 should have been exempt from the helmet law as its safety features are more akin to a car and it is just stupid to wear a helmet in a belted vehicle.

Here's a good one. I particularly like the illuminated skull.

I am a Mortgage Broker based in The Forest of Dean. In my youth I rode a Lambretta Scooter until I was 22 years of age. At age 62 I have returned to scooterring by purchasing a new Honda Silverwing in June 2005. Before I took delivery of the Silverwing I undertook refresher training. I have since taken things steady and now am getting to grips with the bike. The enjoyment derived is tremendous. I attended Peter Billington's open day and was quite impressed with his comfortmax. I would like to say that I am an all weather biker but I may winterise the bike when the road salt appears.

Low CoG limitations reply. This is a reply to David Botting's paper with my comments inserted.

Please find attached a written article covering some of the less favourable aspects of low CG design. The article is in part written as a reply to the theories put forward by Royce Creasey in 'Feet First - The Physics'.

Acceleration
The average sports-tourer has nowhere near the amount of power to make wheelies a serious disadvantage. It is only over a very narrow rev range, between 500 - 1000rpm, at peak power and in first gear that such bikes are able to lift the front wheel from the ground (not the same as continuing a wheelie).

This = just a split second. Provided that a modicum of skill and throttle restraint is applied in first gear, the front wheel can easily be kept on the floor without serious loss of acceleration, and who needs to accelerate THAT hard anyway? It is wildly unlikely that a ‘looping’ situation would occur without the direct intention of a wheelie.

3-in-line STV: A prototype to test the concept, built mid 2002.

Made from a Suzuki 80 step through (free) and a couple of 10” scooter wheels (20 euro). The idea is to test if any of the supposed benefits can be achieved, and what problems there might be in applying these. Middleton Link is a solution to a bump steer problem in this concept.

Benefits are: increased contact patch to unsprung mass ratio, increased contact patch to tyre width ratio, effectively reduced unsprung mass for a given contact patch area, contact with the road with at least one steered wheel on sharp bumps, second tyre running in drier road surface under straight line braking conditions, lower propensity to front wheel traction loss in cornering, potentially lower frontal area and un-steered suspension. Actual mass of the complete system is less than a single Kawasaki GPZ500S 16” front wheel and tyre.

The 2005 Quasar outing will take place in Hastings over the week-end on September 10th/11th. The format will be similar to previous years with us meeting up on St Leonards sea-front on Saturday afternoon from around 4:30pm onwards and moving on to Bo Peep pub for supper. There will be a ride-out on Sunday morning and we'll finish up at the Six Bells at Chiddingly for a late lunch.

All Quasar owners, Quasar enthusiasts, or owners of other Feet-first machinery are invited to join us.

It will be a long slow process, but I'm going to try to document the building of my FF machine on this page.

The machine will be built round a folded aerolam tub, with a cradle under and partly round the engine, continuing into a triangular cross-section box containing the fuel tank and carrying the seat, sweeping up at the rear into a backrest bulkhead, with the swinging arm pivoting at the back of the central box. A tunnel will be formed through the box containing an extension drive shaft. The machine will be about 10 inches longer than standard.

The first two drawings attached show the Hossack style front fork, and the main aerolam spar of the fork as a developed sheet ready to be cut. The drawings are all but finished, and will shortly be going for quotation for NC milling with an old client who has machines capable of cutting the job. It is possible to cut four sets of uprights from an 8x4 sheet of material, so I will have three spare sets that I may offer to the group.

I've posted a load of pictures to Flickr of my attempt at adding a Volvo seat. Click on each picture and you'll see lots of annotations describing the detail.

After much hacksawing, cursing and abuse of power tools, I now have a Volvo seat
mounted on my Burger400K3. Lessons I've learnt:-

- I'm crap at this metalwork stuff

- I should have listened to Royce, the Volvo 340 seat is the best. I was seduced by the fake leatherette of the seat from a bigger model but it doesn't work so well in this application. The problem is the mounting mechanisms on both sides are a good 4 to 5cms lower relative to the seat.

As you can see from the photo, it is possible to fit a Volvo Seat on a Burgman!

This is the next stage in making my Burgman more of an FF. I got the seat from the Volvo Breakers on the A1 near St Neots for a mere 25 quid. It's a leather seat so won't need recovering. I had quite a choice and eventually plumped for an early 7 series instead of the usual 340 seat because of the leather, the filled in head rest and the fact that the lumbar adjust and the rake adjust are both on the left hand side. Not only that but it's got a heated back and seat base.

Hi folks,

During the '80s I helped build a couple of FFs. The first was based on a BSA A50. Basically all that was done was to extend the swing arm, so that a high backed seat could fit down behind the carbs. The steering was linked back to a second steering head where the handlebars were attached. It was a joy to ride, after you'd gotten used to the way it handled and steered. Later it was enclosed in fiber glass. It worked well, visibility was the only shortfall; you couldn't see much over the top of the forks!

Hi guys, especially to some of my old friends like Paul Blez if you're reading this...

I've now owned a Silver Wing for almost 3 years (bought it with 11k on the clock) and covered another 20K+ miles in that time. It has taken me back and forth between Sydenham and City of London every day with occasional trips to Belgium, Holland, Luxemburg etc, without breaking down ONCE!. In fact the only time it has been off the road was for a week after an accident I had with a minicab turning right without indicating. The damage was close to £2K but all is well again and the bike looks as good as new.

Has any one any information about an extende wheelbase on any megascooter ?
Cheers

As promised at Beaulieu, here are PDF versions of the plans used to make the current version of the ComforTmax. As I have an A3 printer at home, all the drawings are that size, so you may have to do something creative if your limit is A4. If anyone wants the (sorry, only 2D) CAD files in DXF or DWG format, please contact me at angib (at) blueyonder.co.uk

All these drawings, except the fuel tank, were made as guides to the guy who did the metalwork on my bike. They are not sufficiently detailed to give to someone to make the parts and they assume you have a Tmax in front of you to work from.

Here's a PDF sent in by Andrew Gibben on steering linkage layout on Funny Front Ends. (FFE)
