<![CDATA[Dt 125 to DT200r engine swap]]>So I’m currently rebuilding a dt125r as nut and bolt restoration and considering/most probably will be putting a dt200r engine in to replace my current just want to know what are everyone’s experience with the dt200 engine, what’s Involved, what do I need, and anything related to doing this swap

Will be posting my build soon when I have a good inventory of pictures to show you all and get you hooked into knowing what’s next 😉

Also they always have super skinny wheels and low boy exhausts 😞

It's probably easier to say which_is_which, by naming the rider with or without gloves. These idiots never ceases to amaze me with all these vids of fast/stunt riding and NO FREAKING GLOVES!!!

Cool vid though, personally I'd go for the 200cc engine as you will get better reliability for-sure. 😉

Both will need carb, pipe and exhaust in the case of 200WR.

Neither 200 engine is bonkers like a YZ engine, however the 200 is like the 125 you always wanted and has more grunt.

The 200WR engine is slightly more powerful than the 200R and has a nikasil liner rather than a plain steel one.

I have a DT200WR and a TDR125 Belgarda and I'm probably going with a 200R lump in the Belgarda just because it will look right and need the least mods.

Need to souce a engine too there’s one on eBay from Poland that I have had a look at but not sure

I look forward to seeing it.

Depends on which DT200R Engine you're going to use, one is vastly superior to the other, 3XP00 I believe is the one you want.

Ultimately, it's still no match for a YZ250 Engine etc, but it'll be a nice upgrade.

Read @Louis-James build as he has that well documented.

Engine should be straight swap, if you want to transplant the cylinder to the bottom end then you will need to do some modifications to the crank case.
