My savage "ROADSTER" custom
08/05/24 at 03:53:38
 
Hello everyone
I am new to the forum so I´d like to introduce my savage route.
I am riding bikes since I am 16 (I´ll be 33 in the September). I always like older and classical bikes. My first bike that I bought as a teenager for my own money was bike from 1975 and I restored it completly. I learned me a lot.
Then I bought diferent bikes always classics or naked bikes.
After years I bought my "final boss fight" project bike that I started to rebuild - its Honda sc33 CBR919RR from 1998 and it is the most modern bike I ever wanted. During the years of rebuild work I tried to finalize my university degree studies, then my kids were born etc etc and I had never time to finish. So I gave it to my local motorcycle service guy to finish it and.... he has it already 5 yers and can not finish it too  Grin
So during that time I bought another bike to have something to ride. And it is my SAVAGE!! finally. But I did not like the look... and sitting position so... I started easy rebuild  Grin
It is not so easy as I thounght in the beginning but it is sloooowly moving forward.
So.
My bike is 1986 savage. 4 gears... old one.



Previous owner was 70 years old dude and bike rode like 10 kms in 5 years.
Paintjob was not original, handlebars were not original (installed dragbars), a lot of mess in electricity cables,... cheap old bike.
So first year I changed oil, repaired electricity, brkaes changed head plug seals etc.. just make it ride. And I love character of the bike. It is light, super simple and engine... by the feeling of ride it feels to me more like oldschool motocross bike (like form 1960s-70s) then chopper.
And I always loved look of classic bikes from 50s, 60s. Nortons, BSA, CB,.... And I always loved old cafe racers but in last few years I feel like everything is café, and sometimes it is too much.. so...
So I decided to make my Savage look more like something called Roadster.
Goals are clear, I have to fit differnt fuel tank, seat, move foot controls. I also want eliminate airbox, want to fit diferent muffler, handlebars and headlight. And in the end I have to make new paintjob.
What I can not do are things that are not easy or possible to make it road legal in my country. I live in Czech Republic and every 4 yers we have to go to oficial control with every bike to verify that everything is ok, working and legal.
So I can not change wheel size, I can not modify frame and change "overall dimesnions of vehicle". All part (mainly lights) have to be stamped by "E" mark for european homologation. Whan it will be finished it still will not be 100% legal but I have to try to discus with comisars.
So the rebuild I started with diferent handlebars.
First I shortened stems.


Original had long stems and the shape was drag bars.


I found band bars in classic shape with right width (to keep width of the bike).
I fit them and it was much better.


Ps.:I need to find out how to upload images and then I will write down what I already did on my bike  Grin

So one of the thing that had to be done was to change head sealing.
There was "little leak" visible


Everything started by disassembling everything


Then I let steel tube bent to make loop


So I welded some attachement ponts to frame to use threads already existing on frame to make subframe just bolt-on.


It fits +-. Seat I bought on aliexpress and fuel tank is from Yamaha XS360. It fits well and looks good in my opinion.


I had to bent the end of the loop little bit up.
Seems fine to me

Welcome to the Savage forum!  A young person that appreciates more vintage bikes!  Cool!

Your photos are visible, and I’m able to see them on postimage (when my fat thumbs don’t accidentally click on an ad).

I like your handlebars.  Classic and functional.

The other modifications you have planned seem reasonably simple, but I’m not a customizer so it’s easy for me to say that.  The gas tank will probably be the biggest challenge and you’ll have to decide what you want to do with the speedometer/odometer when you make that change.  EDIT: you’ve posted more pics with the Yamaha gas tank.

For a 1987, your bike looks great and seems to have been cared for quite well!  Enjoy your build!

One of the topic I was afraid the most was relocation of foot controls.
To keep front chopper position makes no sense.
I realised that is possible to use 4 engine mount bolts in the rear of the engine.
So I designed 2 "brackets" to let them laser-cut and mount them on these bolts. thru these brackets is going 1" tube. On each end of the tube is again laser cutted brackets to fit original pegs and control levers.

Then had to be necesary manufacture some pivot to locate brake lever, some connecting rods to conect shift lever and rear brake etc. In the end it works well and everything fits.



Sometimes I use 3D printeed parts and superglue just to fit it on the bike and see if everything fits befor I make it (or order it) made from metal.



And BTW I made all of the parts two times in case I srew something.
And I did not. So if anyone of you wants the parts I can sell them. Or if anyone of you want .dxf files for cutting to make it also for your bike I can send it to you if you want  Wink it was pain to get right shape of brackets so I´ll be happy to share. It is shame to do all the design job just for one bike  Cool

One "smaller" task is the rear fender.

I bought super cheap stainless steel fender from china. I like the look but I could not realise how to bolt it to bike without frame modification.


It´s nice, but...

I did not want to destroy original fender by simple cutting it.. I wanted to keep it in shelve just for case of future possible "original state rebuild" for controls.
Time to make my own.
I am not so good in metalworking but profesionally I am composites specialist. Carbon fiber is my hobby since I am 15 and I also have master degree in it and now I work as R&D departement leader in aerospace production. And still I work a lot with carbon in my hobby workshop... (I make my own carbon bicycle frames etc)
So easiest thing for me was to make my own carbon fender. Just bcs I know How to do and it is much waaaay easier to make it then to use metal.
And I also can use scrap materials.
I did not want to make mould so I decided to laminate possitive shape on the top of original fender and use it as a mould.

Orange layer is just peel ply textile that is removed after the laminate is cured.


Unmoulding was pretty easy (I used only PVA as a release agent) and fender went out of pretty well.

The holes are there bcs I could not aply material in areas where are some metal thing on original fender. So I left the hole there and after unmoulding I covered it on top by several layers of carbon and let it cure again.

Weight loss is definitely not goal on this build but nice sturdy fender weights only around 300 grams.



I trimmed all edges and tried to fit it on bike. It fits and I can use original bolts holding fender, bcs shape is the same.
Then I just aplied kit, filler and ready to be painted. (I did not do enough photos)

In the last picture you can see template I use for designing underseat case. I will make it also from carbon.


And here is cone filter that fits to my engine

I need to be sure that there will be enough space for that under-seat carriage case and for the filter.

Fronk suspension was heavily leaking.
So I had to disassembly forks.
When it was in process I used that oportunity to modify heigh.


It is hard to call it "build" when it is less and less parts on the bike in some moments  Grin


I think that all of you know that you have to make special tool for complete disassembly of the fork leg. I did it. Ready to modify


I designed and ordered manufacturing of the 50mm spacer

Made of stainless steel on lathe. I wanted to have it precise.


Then I shotened upper spacer in the fork (50mm) installed new sealings and washers etc and assembled it again together.
I used heavier oil to compensate shorter lift and I felt that forks were too soft anyway before modification (maybe I am just used from sport bikes?)
So now forks are 50mm shorter. It looks much better.
In that step I installed headlight holders and installed bigger headlight. Originally it from some naked bike... I don´t know but I don´t care too much. I like the look and I am sure it will shine enough with H4 bulb.
I also bought some cheap speedometer and RPM meter and installed it.
I have not connected it yet. But I installed them just to see if everything fits. I like the look now!






Real fender is not on photos yet.

Thank you! I am not sure that I can be called "young person" anymore. But thank you for compliment  Grin

I finished this small detail yesterday.

I used old bicycle shifting lever as a manual decompressor.
