Cool man, get rid of that 16 on the front .

[Ivan]

ill get it going then worry about that

Starting to look the part Ivan, not too many people build whole bikes so good on you.
I have a SDR200 swingarm if you want it , a bit heavy but has a linkage and looks pretty cool

[Ivan]

how much for the sdr swingarm? it looks the buisness looking at photos ill get some proper photos after i knock off work for year have afew things like swing arm to make and really wanna get some better front forks those chinese onesimade aint going to work and the whole front end is currently 8kgs!

[Ivan]

that photo ive got up is so shit it does have along way to go before being ready asI want it to be perfect and its going to go to a engineer when done to make sure the thing aint going to break on me theres alot of thought gone into this its not going to be perfect and theres going to be nit pickers but im proud of it so far

Re the forks from post #7
The Aprillia RS125 trip clamps will work, are strong and don't weigh much. Ditch the chinky forks and use some RGV250 USD's. You will have to shorten them by around 75mm but will be a much better fork. Brice Minto from Buckets and bits in Welly has some for not much $'s.

If you had a real solid fixture in the shed you could fit up a mandrel to go through the steering stem. Then rig a loong bar through strategic points & lean on it. Will tell you how much it will flex & if welds will hold (vibration aside).

Very scientific...

ahh, worked for that Foales chap.

[Ivan]

my uncles a engineer and is round here all the time so will get him to look over it thanks for the advice,


I will get around to some RGV forks when I have some money at the momment ive got to many other priorities to spend money on so this is getting the cheapest options at mo,


I was actually thinking of getting some conventinal forks of say a mb50 etc and making them fit then playing with the damper rods to get the front end to work as good as I can get it without paying big money for emulators,

[F5 Dave]

MB50?? they are about 25mm!

[Ivan]

MB50?? they are about 25mm!

lol i just threw a name out of the air dave haha

[Ivan]

rg 50 forks probably wouldnt be to bad i cant remember how big they are tho, Ive got the Aprilia RS50 forks still they would be good but need to have them machined down quite alot to make them fit plus I think Kyle wants them back but they would be the ones i want I reckon

[Ivan]

and after all that time building it off measurements i sat it next to the rs125 everything lines up the same sweet!!!!! one problem a frame rail when mounted was mounted on a angle and its made that out of line it wont affect the bike but really is annoying the tank sits flush on one side and one theres a gap will probably cut it out and weld it back in the correct place
