wr200, it has been done before on the german forum

1st got to sort the topend then

open the transferports on the cases

the wr has 57mm stroke the dt has 50.7mm

i am fitting the 57 crank, which i will have to open the crank cases to fit it, the crank bearings are the same size as the dt

heres some pics

see the only difference between the WR and DT case in the pic is the crank housing

Looks a good plan does that, am starting a bottom end rebuild soon, may see about banging a 57mm con rod on the dt crank if possible. Norfe how easy it to split up the crank, to replace con rod?

gumtree mate plymouth, he had the bottom end for sale aswell, but that would have cost me more, and have to collect it,

the barrels plated as standard and has very good porting

3XP00 (wr200/dt200wr) or a 3ET00 (dt200r)non plated and no exhaust ports

A ha ha , And much faster than the athena 170 :( I dont think this is any fun at all xD.

But im wondering something, is it the same bearings on the wr200 as the dt 125 ? or are they just the same size ?.

 same size and the part numbers are very similar, but i think that they might be different quality,

Theres no way to be shure really if my crank is gonna be able to handle the 170cc in the long run.. But for you, Your driving with the crank of that cyllinder so you can guarantee its gonna handle it.

And the 170cc is only 166cc in reality, And considering i used to drive 1,5mm overbore that made my cyllinder 130 cc, Wich means the 170cc only gave me another 36cc.

Thinking about it that way it doesent sound that much harder for the crank, Or that much stronger than the stock cyllinder xD

could you not just buy a wr 200 con rod kit and fit it to the dtr crank?

isnt it just a longer rod, or is the crank pin in a diff place?

 I were thinking along those lines, maybe using a wiseco DT crank mind
