Went and got the DT100 from Yumastepside's place.
Its actually a lot better than the photos would have you believe, although the right-half-black, left-half-purple frame is quite hard on the eyes...
The dubious flame paint job is actually quite well done, so I'm leaving it there for a laugh.
The nice fork tubes will go onto my MX125, while the DT will get a set of 34mm forks (I know these are outside Firko's suggested rules, but WTF - at the moment there's no official class so I will use what I've got).
Everything else will come out of my parts pile - just the 'best of the left over' parts that I drag out of my shed...
It might yet make it to CD6, depending on which trailer we use. Assuming the bike works OK, anyone who's interested in having a ride on it, just needs to ask.
