Here you can find a few bits I made for the SB5.

Headstock: considerably lighter than the Original.
Rear Swingarm that should be stiffer than the Original Kit thingy.

Keep in mind that those parts are PROTOTYPES!

nice work edi

you are liking the shapeways site??


the rear swingarm box.
you have it marked as making the rear of bike 5mm higher.

should this be used with the longer front forks??or does the bike need to sit higher in the rear?

cheers
a

p.s.
my sb5 should arrive next week

The 5mm higher Rear was a wish from Mr.Zonzini. He said that the bike will turn better when its higher. It hasnt been tested yet we will see.

I will be bringing on further parts in the future and they might be making previous bits obsolete. But "HEY" all of you can try prototype parts, no risk no fun.....

One thing I am working on is a improved front brake assembly with the option to flip it Left/Right. But I am waiting for the servohorn made of Stainless because I dont know about the qualitiy of the parts. Once thats okay I will release the parts.

if you are talking about the printed stainless, i doubt it will be good enough.

it will require machining on virtually all working surfaces, the finish will be almost like a polished sand casting.

the stainless does machine nicely though.
i have made a couple of parts with it.
but like i said. treat it like you are getting a casting made, unless dimensions and surface finish arent critical

i havent done any destructive testing on it yet, but it machines a little easier than normal stainless, but much harder than the bronze that it is infused with.

wil take some pictures of other parts i have made previously and send them to you

cheers

Hey guys... I've just finished assembling my SB5, and now sorting out the electronics. Problem I've ran into now is the brake servo, I know it's been mentioned here before, but I was hoping that there was another option for a replacement, other than the Sanwa unit... Being Australia there isn't always a large variety of parts around...

Anyway... My servo lasted about 30 seconds running with the digital steering...

I believe the Futaba S3156 servo will fit.

my dive into rc motorcycling has trully begun
the sb5 arrived on monday.

i have fitted a futaba bls551 servo.
issues with the steering.

i had to mount the servo with no spacers under it.
it required a couple of mm to lift it to the recomended 17mm in the instruction manual.
but there is not enough clearance for the servo mount or the heads of the cap screws to pass the pivot of the lower suspension arm.
with the servo flush it has about 0.005"

with the servo mounted flush the steering damper/spring assemblies foul on the front pivot of the upper suspension arm.
so i have mounted the dampers above the servo horn.... this isnt ideal geometry but should still give a nice consistant action.

and finally
the damper assemblies actually rub on the inside of the upper suspension arm(both sides), i will be removing the mould line and maybe a little material to give it minimum clearance

cheers
