Cyclinder head

What years of dt's come with the 3mb head? Are they the same size and fit as the 3bn jus without the squish band?

Unsure of the year bikes they were on, sure someone on here will know but yes they are the same fit as the 3BN just without the restrictive squish band. I recently swapped my 3BN for a 3MB.

@Burridge. Did you notice much of a difference?

3MB's came standard on the DT125RE/X 04'-07' Can find them on late 2002-03' R's.

The 4DL has the best head, Stamped, P

@kennymurphy97 it definitely gave it more compression as I could feel the bike vibrated quite a lot more. Was going to get a compression tester for a before and after but forgot all about it. I hadn't ridden the bike for a good week or so before changing the head though so can't accurately say if I felt a difference in power or not, although with more compression usually comes more power. I should be getting my new exhaust soon so I can make the most of it.
