Downsizing the cc, txt pro 300 to 200
 
I wondered if it's possible to downgrade the 300 to a 200 barrell D piston?

I have a txtpro 300, but find it a bit of a handful to ride, I have been recommended a 200, so I wonder what the difference s are?
If it's just the engine then is it just the barrell and cylinder? And therefore can I just change them on it?

The old TXT200 was built on the 125 and had different cases. Bet not much has changed there.

Cheaper and easier to sell the 300 and buy a 200. The 200 is a great engine. Does what you want but doesn't charge off in a different direction when you give it a bit more throttle than perhaps required. Saved me many times.

Old thread, yeah, I know (but then this forum is a tad slow :) )

I have a 2020 TXT300, and I've thought the exact same thing. Dealer only had 300s, and had sold the only 280 they were alloted. So home came the 300.

I also had the idea, hey, just get a complete top end, right?! Till I saw the price! I guess a more progressive throttle tube and more/longer learning period it will be!

have you tried/investigated changing gearing?

No, but it's worth considering. I'm also going to look into the different throttle tubes.

You can also add a spacer to the top end, and a second base gasket, lastly retard the timing a bit. All will soften the power and make it a bit easier to start.
