Its a good clean project and it will restore well john, the unwanted Frame mounts have been removed, the frame will need a sand blast and painted, the engine runs beautiful, only needs a lick of paint, I have Brand new foot rests, and new foot rest mounts, new rear brake pads, new Red wing rear shocks, new Airbox boot, new air cleaner cage, new sprocket locking washers plates, new intake manifold, another set of front forks and the chrome is very good, fork seals, new alloy tank cap. Brand new Tank and guard decals, the alloy rims are original and in very good condition.
$2100 price is firm, thats what it owe me. cheers Dave

Hasn't it got a RT1 frame?.....maybe you shouldn't be advertising it on here as a DT2 MX250?...but a bitsa.

it looks similar to an RT1 frame Davey but the rear loop is definately not RT1...
i don't know that much about the DT/RT2 MX frames...
it sure would look nice if you finished it though Dave...

On the head stem, it is RT1.

Even though it's stamped RT1 it's an RT2MX frame, not and RT1, they're different. Somebody buy it and give it a life. Please.

I'm not 100% certain Dave but I think RT2MX frames were stamped RT1 and DT2MX frames stamped DT1. Iain would know for sure. I think it'd be an easier sale if you could tell potential buyers that the frames' definitely correct....even if it is a 360 frame with a 250 motor.

If you mean RT1 and RT2 trail bikes that's not right, they made squillions of them. The RT2MX and DT2MX (like yours) are totally different bikes and although pretty rare, I'd have thought they made more than 500.

Iain Told that the frame that I have is worth more than the hold bike, only 500 rt2 mx motocrossers where made world wide. I am not talking about trail bikes, I just won`t the bike to go to a fellow
that will restore it and use it., I am not going to finish it.

If that's true that they're so rare Iain might just have a point Dave. I've got two RT2MX engines, one in my flat tracker and the other in my under construction Hindall framed RT2MX. I didn't know they were so rare 8). Maybe I should buy yours for the frame and fit my motor and make a killing on the collector market ;D.

I didn't say that only 500 odd where made , that # belongs to the yz 360 aprox 513 made the RT2mx was not a large production # but are rare in these days . the DT2mx and RT2mx share the same frame totally different from the DT\RT trail bike frames .As these bikes where Yamahas first production motor crossers built from the start as race bikes . the DT1mx was built from the DT1 trail bike and used a standard trail bike frame whereas the DT\RT2mx had no brackets for lighting or indicators no steering lock the frame also had 2.5 inch lower rails to clear the over the head cross pipe  . Yamaha used both the DT1 and RT1 prefects on all dt1 ,dt2 , dt3. rt1 , rt2 , rt3 , frames the main differences are 18" front wheel to 21" by late dt1 early dt2 ,reed valve in 72 . So as the DT2mx and RT2mx where classed as dt and rt bikes they kept the range frame and eng # s . I was interested in Daves bike when it was first on Evilbay as like Firko I have a Gen RT2mx motor the price was at the $750 mark on the bidding I would have gone a bit higher but the bike was going to be a parts bike for me not worth spending much more . The bike now is over priced sorry Dave you should have called me before spending on all new parts from the US , I told you before you started on it I have a shit load of bits for them . As a collector the bike is intact BUT even thought the frames are the same they are numbered RT and DT this bike is a hybid with a RT frame and a DT motor , this will not mean anything to a racer but to a anal collector like me they have to match not necessary matching numbers but the prefex have to .

G465b I would check your numbers for the RT2mx there was no way that 13,067 where made . Iain
Title: Re: 1972 Yamaha Dt2 Mx 250
Post by: Iain Cameron on December 16, 2013, 12:21:09 am
SO to sum up what dave has is a RT2MX with a DT2MX motor in it . there is no need to add 250cc to the decription  or add a space between the DT2MX as Yamaha used the first two letters of a model # as the code for eng size . It was not till 74 that all trail bikes where called DT's till then it was HT 90cc ; LT 100cc ; AT 125cc ; CT 175 ; DT250 ; RT 360 ; Im going back into my hole in the ground, talk about anal . Some times I wonder at the amount of Yamaha facts and knowledge that invades my brain . Iain  :o :'(

Sorry Iain for thinking that there was 500 RT2 where made world wide, my mistake. If know one on here wants it, I will take it to the Ballarat Swap meet in February.

Post by: g465b on December 16, 2013, 07:40:35 am
the numbers and codes I put up for DT mx and RT mx models were given to me decades ago by a long time yamaha dealer( still sells
some rare yam spares) and were mostly verified when the internet came along. cyclerestorer.com and yamahaenduro.com(great site for
all sorts of yam stuff) are two that come to mind.had a DT2 when i was 14 and 39 yrs later have 13 DT/RT yams in the shed.
cheers g.

It amazes me how much other none related comments process on here when the point of this thread is about selling a bike.  well RT2mx or DT2mx, its still the same design frame, and at the end of the restoration who ever completes it will have be a very nice bike to go racing on next year.

No shelpi Yamaha numbers don't work that way . All early Yamahas start with xx xx101  so the first bike off the line will be xx xx102 . Iain

When getting production numbers its best to use the model numbers the DT2MX is from memory 324 and the RT2MX 322 . this 3 digit # is model unique eg the 68 DT1 trail bike is 214 . From 74 Yamaha used these numbers in eng and frame numbers . You have most probably got fed up with my ravings so Ill sign off . Iain

According to my list there were two number sequences for the 1971 RT1-B (black tank/red pinstripe) 73101-75128 which I don't understand as it doesn't even follow on from the previous 1970 RT1 (black tank/yellow pinstripe) which ran from 50101--57218. The second group of listed numbers for the RT1-B are RT1-009101--024820 which would make yours the 9th RT1-B off the production line. There's a zero missing from the beginning of your number sequence but that may have been lost in translation. Can you check again? If right, you've got a very early 1971 RT1-B piston port.

Thanx Firko, no typo, so it is a very early 1971 RT1-B piston port, black tank red pin stripes, did check and the number given is correct,
I am still after a bottom end for it

So that explains the two number sequences for the RT1-B. To be honest I've never heard of a close ratio RT1 but I guess this info tells us they exist(ed).
