DT 125's (some more power than others)

[Torque-head]

Im planning on moving from a TDR to a DT 125.
I've been looking at the bhp of different models(years) and am wondering if anyone knows what the best year of bike to get.

I do like the TDR but everyone keeps telling me that the DT has a bit more power and is much more fun to drive.

The fact that the engine of my TDR needs a rebuild kinda makes me want to try a different bike.
I will soon be moving to a CBR250 so i just need something to last me 3 or 4 months.

Any adive would be great

Ye but the bearings in the engine of the tdr are really loose.
Believe it or not i was quoted 1000 euros to have the engine rebuilt.
So my plan is to sell it Quick , and either get another TDR or a DT.

The DT i'd be gettin is a 99 and fully de-res.

If you can get the DT for either no money or very little more than you get for the TDR then it's worth it, otherwise I'd just stick with the TDR for now mate.

DT125R restrictions and de-restriction can be confusing and difficult depending on the year. But assuming the late bikes, have no internal engine changes, Then they should all be capable of the same bhp when fully de-restricted, which is the trick bit. A full power DT should put out 20-21bhp approx at the wheel. This corresponds to the original claimed 25bhp at the crank for the early full power models. later full power DT's 2000> i think when sold in Japan and other countries that dont have 12/15bhp learner laws are claimed to have 22bhp.
The easiest of the DT125R's to de-restrict is the pre 97 models, that did not have the YPVS servo or pulley housing fitted. Apart from the expense of finding and fitting a servo motor, cables, and pulley etc, there was only a single exhaust restrictor in the front of the downpipe to remove.
DTR's from 98> had the YPVS system but it was not fully operational, in that it does not open fully. I have heard that to get it working the pulley needs modifiying or changing, and the cables need to be re-adjusted. These later DT's had up to 3 restrictions in the front pipe, and so a performance pipe is needed really.
The jetting and the oil pump settings are supposed to be different on the 98> DT's and i think restricted they use around a 210MJ and this needs to be about a 240MJ in full power form.

The latest DT's are different again i think, as though they have restrictive pipes with cat converters fitted, they have an electrical restriction that is something to do with fitting a fuse to a connector block under the seat? These bikes only make a claimed 20bhp at the crank, afterwards, but the pipe std pipe is not much good and so a DEP etc should add a fair bit more poke to them!

The std TDR's never even made 12bhp, as they were the same as a DT engine, but they had a Cataylst fitted, which really restricts the power, but swap the pipe, and they should be as powerful as the DT of the same year!

And as for looking for a new bike, when if all thats wrong with your TDR is the engine, then i cant see any point in getting a DT etc, as it would be cheaper to re-build the TDR motor, than buy another bike, and anyway the TDR is much better bike for road use than the DT anyway!

lmao, comic

its the same frame and same engin and same barrel only the front chamber thats differnt matey and the gearing.

Get a dt125 rear sproket , and a dt125 from exhaust off ebay (non restircted one.

tdr got LOADDDDDSSS better brakes and road suspension
