@markus-w ok, thanks. Hopefully someone will be able to answer my question even if it is an old bike.

@Scootjockey Every new piston I’ve brought for my Dtr has been a 3mb TZR piston. As long as the bore size matches the Dtr barrel, then all the porting/cut-outs and ring pins are in proper places ... TDR pistons however are totally different ...

@rraleks My piston ate away because of overheating and a weak mixture. It was the beginning of my head gasket adventure, IIRC

@markus-w The KTM lc2 use a 520 chain on the water-cooled dtr 125 engine. Maybe you can fit a bigger front sprocket from this bike.

@jaimegonzalezlu yeah it looks suweet in that photo!

@edfrearson Be a fool not to if the weathers good. It’s gonna fly! Smiles guaranteed 🤩

@ringo67 isn't that always the issue and yeah not sure on emissions

@spookdog sounds like my old lady....she keeps saying she's strawberry blonde but I took a photo of her to work and they all voted "rip roaring ginger "!....lol.

@calum I will agree with you about the sweet spot....RD 125, 250 ,350 ,500 not counting the 50 or air cooled modles as well as rgv 250, 500 plus the Dt modles......CR's....KX's the list goes on..its just the sound and smell of a two stroke preferably with a non standard pipe/s . As for electric bikes I'm coming round to these as I like some of the e-mountain bikes but at around 3 grand for a good one I can get a well sorted DTR for that. Plus I've had motorbikes since I was 18 and have never considered myself a biker but just love riding and tinkering with them. But due to my wife being ill and work have had a four year break and I'm now looking forward to getting back into them and getting a DTR is now the goal.

@calum Sorry about that dude haven't had to link images in years, used to be into bits of coding and stuff aswell would you believe xD I'll work it out on the next post, been posting from my pc. Monday i'm going to revamp her fullly so will do a build thread Hope everyone is safe and well!

Hello “old” I am “young”. Age isn’t an issue around here, if anything it’s welcomed. In your case you got to live in and enjoy an era of biking that’s now somewhere between a daydream and a winning lottery ticket for us to be able to enjoy once again. Not that it’d ever be the same. For that reason all the stories and experiences you have are a gold mine Good to have you here mate

Welcome to one of the most knowledgeable, friendly and helpful places on the internet if you’re a yammie nerd or just a gener all round good guy with a love for bikes, namely old two strokes

Hello welcome! Nice, what's condition is the bike in?

Clicking the background area behind that will give you the option to upload a photo for your profile, the same applies for the icon for your name Hope that helps

@Schonker Welcome to the club, post some pics dude.

@ifixbikes nice

@Calum hi all i changed the front to a 15 now and its fine now does 68 in 5th and should rev out in 6th should do about 80 but haven't had a open road with out traffic, very strange to lower the std gearing would this been part of the restriction ?

@gibboharps Welcome to the club dude!

@Darty Not much to tell as yet - ran the mic' over it and put it on the surface table to check true / balance...so far so good. However whether it's chocolate, or had poor heat treatment, etc...time will tell. I'll post as I learn about it.
