Re: Bushmechanic frame Build pics and Stuff

80-90kgs sounds like fun....
but what about trying to get the balance point back far enough for the big ugly 4smoker in a 2smoke frame, may need a little more than 50mm on the headstock to try an lighten the front, and no the throttle does not count as a weight shifting device (coz sooner or later your guna haf to close it).

Re: Bushmechanic frame Build pics and Stuff

Im using a ktm 85sx because you get a full sized shock and nice 43mm forks, the rake is 24 deg, if I go to 30 the wheel base extends about 70mm, 120mm total extension at the front

cheers aquajett

gearbox broken again so more time for building stuff, I think im supposed to mow the lawn, paint the house or something

frame weight is at 7.5kgs so far but got a few little lugs and the subframe/airbox left to add so I guess it will be 9-10kgs. the stocker is just under 12kgs and the first one i modified ended up (15kgs, big boned)

adjustable top shock mount


husachopper mock up for Bergbro, exhaust will eventually be 2 into 1 right out of the head

rides good, turns way too easy does everything right so far, rear and rear of seat are up too high will drop it down and or lower the subframe.

rear wheel shows 50.5kgs and front 48kgs bit more stuff to add, tank maybe a sort of airbox and a rear guard should be about 102 kgs without fuel

Re: Bushmechanic frame Build pics and Stuff

not really beautiful yet perhaps but a bewdy maybe

the added trail and rake is awesome in the sand, I did all kinds of stupid stuff in the whoops today and didn't feel like the front was trying to kill me except when the seat kicked my butt, i gotta drop the subframe.

cradles nicer in rocking chassis movements partly due to the more harley rake that I feel is making the forks less prone to blowing through and without the bulky tank i can sit right up the front so front end corner grip is sensational

lofting the front is much easier, lower COG makes its tip resisatnce really low and loosing 15 kgs makes it go like a rocket

the nicer swingarm angle gives more traction and the chain pull moment does its anti squat thing mid corner with the power on, the roadbike guys aren't kidding when they say chain pull moment is at the centre of the motorcycle handling universe.

I love this thing, just like a new bike

its ended up

wheelbase 1570mm (1480 stock)
rake 31.5 degrees (27 stock)
trail about 150mm (about 110 stock)

swingarm pivot height both wheels on the ground 450mm (460 stock)
seat height 930-940mm with corrected subframe
ground clearance 320mm (380 stock)

wet weight but no tank or fuel 100kgs (say 115 stock)
and shed loads of 700 tourque

Fun project Bushie!
Brings warmth to my heart to see creative, and committed people!
There is space for a down-drafted intake, isn't there?

I think that within 2 years "all" dirtbikes will have box frames to give space for a more effective shape of the intake port. Remeber where you heard it first!
