Hi folks,

I'm from Oz, ride a wobbly (BMW) and am currently working on an 1150r. I do the majority of my own mechanicals (unless it involves expensive, specialist, use them once a decade tools.)

This bike like all the others before it is a daily ride (300km a week) so from a design perspective I don't mess with the steering geometry. (This includes ridiculous tyre and wheel combinations) and I build for longevity, repairability and road registration without brutally expensive engineering certificates. If it's beautiful but unrideable then it isn't a motorcycle anymore, it's a large, expensive ornament.

Rs,

Sol

Sounds like you might fit in here. Unfortunately, traffic has been light on the forum lately.

If either of you folks have ever used POR15 clear coat I'd love to hear your experiences. I put a post in the tech section about it.

Welcome aboard, Sol! It's great to have you with us.
Thanks mate. This is a project very close to my heart. The guys on R1150r.net have been good to me over the years with brilliant technical advice about the bike but I realised they probably didn't want to hear my crazy questions about customising it.

Although custom BMW build are common in the US and Europe they have been much rarer here. The bikes were traditionally quite expensive and I think people didn't want to take the chance of messing it up.

The 1150r is my favourite model of oilhead roadsters and when I looked at it all I could think was "This is the kind of bike people will café racers from in 30 years, why not do it now?" I like the the unapologetic chestiness of the design. but to see it felt as if the designer had stopped at about 70% of where it should have gone. ( I understand they have to build for the 99% and not the die hards.)

I mocked up this concept and sat it on my fridge door for three months. My thinking was that if I still like the idea after that time I would give it a go. The "strong forward" but short tailed look of bulldogs and lynxes was feel I was aiming for.



This was the final result and I was very fond of it.


Where possible I used legit BMW parts and maintained as much factory functionality as possible . The bobbed tail was all custom built, flat sheet mild steel hand shaped with a dishing stump and hammer but it all still locked and opened with the original BMW mechanisms. The underbody work was a nightmare, the original parts interlock at a lot of different places which made it hard when the sub-frame was shortened but 2mm Kydex ended up being my friend. It can be heat shaped to beautiful curves with a bit of patience. I did change some things after this. The headlight mount ing was dropped and moved forward to set the centre line of the light to match the centre line of the tank. This gave the bike a more "striding forward" feel. The original was a bit too "prairie dog" for my taste. The mount in the picture was only a prototype to check that it would work but I ended up doing a CAD plan for it that was a lot more elegant and factory. Ended up with a laser cut version in 2mm stainless.

Alas she and I took a wee run down the road in a sideways position so this is my second go. I bought her back from the insurance company and bought another another bike (same year, make, mode and colour) and started again. The first go taught me a lot and I have changed a few aspects of the aesthetic. A lot more silver highlights, polished parts and pretty soon a spoked wheel set. The side panel arrangement continues to vex me a bit. The bike has a rising angle through the tank, sub-frame. that I want to honour. A traditional "flat" café racer tail and seat will clash horribly with those angles. It's going to take some hard thinking about the best approach if I go down a more old school aesthetic with the seat, side cover, tail, sub-frame assembly.

Anyhow, enough of my yammering on. Thanks for the welcome.

Sol.
