TECHNICAL MOTOBRICK WRENCHING In Remembrance of Inge K. => Project Custom Motobricks => Topic started by: 850Commando on April 16, 2017, 09:06:26 AM

Hi All - Massively inspired by the stuff on this site (in particular builds by beachcomber and jc55) so decided to try to make my own K75 Special, So far just acquired a 1993 K75RT - Due to limited time and no easy access to workshop I'm gonna try to achieve maximum effect with minimum engineering input (cos most of you guys seem to have engineering skills and know-how I can only dream of). Any advice or comments will be gratefully received.

Yep sell me that faring if not damaged

Hi Elipten - I won't be needing the faring but you're a long way away and its a bulky item
-
I'm only the length of the M11 from you so I could get interested in buying things you take off your bike. Let me know as you progress.
-
Will do Glacial..
-
I'll be tagging along.
-
hey thanks JC

Starting with the front the clocks are a problem.. Just too big.. I've googled a ton of photos of K75/100 cafe racer specials but nearly none use the original clock pod.. Trouble is, from reading I'm forming the view that changing the clocks and maintaining most of the functionality will probably take pore work and time than the whole rest of the build.. so I've been looking for ways to work the original clocks into the design.. I found this bike:
http://www.motorcyclespecs.co.za/model/Custom%20Bikes/BMW%20K75%20S%20Cafe%20Racer%20by%20Hammer%20Kraftrad.htm
The Monza fairing allows the clocks to be concealed.. I figure it may be possible to mount them on the spider that suppports the headlamp so they dont move with the forks.
So I;ve got a sharp 'monza' style fairing designed for a R series BMW from 'flatracer' in London which I think will fit with a bit of tweeking - Thi sis one of their pics of said fairing on a boxer:
-
Also got some cool - semi raised 'strap-ons' from Flatracer:
-
.. I mean 'strap-ons' :) (is there any way to go back and edit a post to correct typos? )
-
Strap ons?? Really - freudian much?! :hehehe
Yes there is a way to edit posts but only later when you are a more experienced motobricker...
Though rumour has it that Johnny has the power to bequeath all sorts of honours on those he deems worthy

(is there any way to go back and edit a post to correct typos? )
That isn't a typographical error; it's a libidinal disclosure. :giggles
I think this new name for these parts is trending and you're among its vanguard, Commando. The following reference though has just the right touch of S&M; it would be hard to beat that one—if you'll pardon the expression.
I found both parts at DCC and ordered the 41mm strap-ons. In order for the strap-ons to fit, I ended up using a little brute force and a pair of pliers to widen up the openings.
-
Very interesting. :popcorm
-
I'm loving this build already. Race fairings with the original gauges are gonna rock!
I didn't cut the front ears off of my tank because my front fairing mounting points use those. I'd suggest keeping that option open.
-
Hi JC55 - yes, I'm leaving the tank lugs to give a second point of fixing for the fairing lower 'wings'.. LED headlamp arrived yesterday -
-
...I've just got to 'bite the bullet now and start pulling off the plastic. Stage 1 is to get the rear frame shortened - I got a loop from a shop in Madrid but now I need to find someone to do the welding (it crossed my mind to buy the kit and learn how but having read up I think it may be difficult - so gonna ring around some welders on Monday..
-
Also got a seat from the people in Madrid .. apparently it should fit without too much trouble...
-
Sub'd. Please post pics of your continued progress. I like that front fairing you picked out, it should look really nice on your brick.

Hi.. Thanks MauradeRS.. Trying to find someone to weld up the rear frame loop - that's the starting point .. trouble is I don't have a workshop so I have to wait for a weekend without rain and start the strip down in the open.. then there will be no turning back - I'll post pics as I go.. I'm hoping the fairing will look good.. Regards
-
2 years have passed but I've started - Lopped off the rear frame and decided to bolt on loop rather than weld (because I don't have the skills) .. rear loop I got from a custom shop in Spain needed some 'bending' to slide into frame tubes neatly..
-
Bolts will also provide location for indicator and removable bracket to fix original luggage frame (I want to use the bike for touring - not just posing).
-
Going for 'Classic' style so got 'off the shelf' aluminum rear mudguard (fender).. Cut it back at the front to form a square 'tongue' which covered in inner tube rubber is a snug fit in the gap under the battery tray negating the need for an awkward bolt fixing there..
-
Very good. How are you getting on with your "strap ons" :giggles

They're a distraction. Bike would be a lot further along without them.
ETA: Love that chrome rear fender, it's a great touch.

Don't you mean How are you getting off?

Don't you mean How are you getting off?
Indeed.
Dildo's for hand controls must make for an interesting ride...

Hi DJEwen - Still struggling with the 'Strap Ons" (SIC) - :) = Sorting the seat next - The seat I bought from Spain won't fit (My bike is lowered by 12mm and I needed clearance for the mudguard/fender under the seat - anyone wanna buy a unused black dual seat?) - Resorted to making a seat from Plywood - Gonna use the original key lock - It's almost ready to send off to be upholstered...
-
I'm making progress with the seat - next off to be upholstered. Cut side panels from 2mm Aluminium -
-
Just got my seat back from the upholsterer - Fits pretty good using original key lock for easy removal - It's longer than ideal from a style point of view but I want my wife to come on longish rides so a compromise was necessary

No chance of a sore backside on that arm chair.

This project was taking forever but now with 'lock-down' I've had time to move it forward - Made switch plate ..
-
fairing was made to fit a R-bike so had to do a bit of work to make it fit - I think it succeeds in enclosing the otherwise 'too big' instrument console - My main idea was to avoid having to change the speedo/rev counter as from post on here it's not a simple job .. Now just got to to finish the side panels

I particularly like that fairing. 112350

Hi Atlarge - It came from Flatracer in UK but needed some mods to the mounting 'spider' and trimming of the fibre-glass to get it to fit.. http://www.flatracer.com/bmw-fairings/4583977035
-
Lookin good! Glad you’re back at it :popcorm
-
Thanks to lock-down (and masses of advice from people on this site for which I'm very grateful), I've managed to get this build finished .. Everything seems to work and rode it down the road 100m and all seems okay.. fingers crossed..
-
I like that. Fairing does a great job of blending the gauges in.
-
Bonzer work! Sleek seat looks very comfortable
You give that seat pan a few coats of polyurethane or some type of wood sealer?
The plastic/rubber bits and bobs need some 303 protectant or the such
What color you going to paint it?
-
Hi herseyb - Cheers - The whole strategy was to avoid changing the clocks because from what I read (here) it wasn't a simple job.. I think it works - but adapting the R series fairing to fit involved more work than I had anticipated.
Thanks volador - yes - primed and painted the base with Hammerite - I hadn't heard of 303 but googled it and it looks good stuff - I'm getting some - Still trying to decide on final colours - Gonna ride it around like it is for a bit in case any modifications are needed
