You may struggle to get decent 60mm pistons with a 15mm pin bore. Nothing commercially available from Wiseco, Wossner or Pro-X as far as I found. If you find anything then let me know.
Anyway guys I put them on ebay, cause I dont know how much they really worth. I wanted to leave them for my bike , but to get them re-plated I will need to send them abround dont have money for that+ I started re-building RZV500 so need money., but I am open to reasonable offers, cause the big bores from tyga cost around 1200+ euro so figure yourself how much these can worth.
Just to give you an idea I am looking for around 400-500 eu for them.

Look at the link I gave above, they have 4-5 different pistons with 60mm bore, with a pin 15mm,
Got to wonder why he's not using them himself they`ve got 85hp in them!
85hp...
Big bore NSR`s... the ultimate in diminishing returns! TYGA`s, with all that development over the last 10 years, puts about 5hp on a good MC21. There`s one in classifieds now with the works thrown at it by TYGA themselves... thousands spent, 72hp! Where`s the other 13hp come from?

You know, I thought just that myself. Hell, you'd be crazy to sell them with 85hp!
As I said the guy that had them on told me that ( if you have read more carefully), I have no idea what HP NSr will be with them, or if he was lying or not.
+ you dont even know what he had on the bike , you are telling it is impossible to push NSR to 85 HP?
First read then talk.
And as I said I dont want to modify the bike neither have time or money.
Dont like it dont buy, whats the problem?
Go pay 1300 euro for Tygas- there you will be sure what you are getting.

Have ever heard about Polini before? I dont think so, they have been in business since second world war, I think they also do have some expirience in modifing 2-strokes.
What there to develop for 10 years? Ports + bore, optimizing the compression and etc. Everything was developed before Tyga even existed, read books.
If you read the right books, youll know that a pukka RS250 gp bike of 91 vintage only produced 82 hp. _________________ Proud Father of , 05 ktm 400exc supermoto 2018 honda crf rx supermoto

Thats a 250cc, hello!
Where did the 58cc difference went, or you think it does not make any difference
And if you have read the books you would know that TZ250 produces 87HP, as an example- 249cc, just so you know
But anyway, enought discussing that. it makes 45 hp with these cylinders, everyone is happy?
I actually opened that topic to see if anyone knows about these cylinders and can comment something that makes sence-all I got is a bunch of childish comments and people showing off their Tygas.
