I sold one. They have a Derbi engine and run real good. This one was an early one and they had ignition problems but the new stator has never missed a beat and the bike has been durable. Parts shouldnt be a problem as i ordered some stuff for stock and they had it back then.

The GasGas 65cc bike has a Derbi Engine? Like the one in the picture?
This is a picture of my Derbi SM50.
How about the GasGas 50cc SM bike. I am pretty sure it is not a
Derbi engine.... But what do I know....not much for sure.
I asked here a few weeks ago about the motor in the GasGas 50SM.
I think someone said it was a Minarelli. I'll have to go back and see.
Thanks for any clarification.
Jeff, So. Cal.

Where are you in New England? When I was at the only dealer (that I know of anyway) in New England, New England Dirt Riders in Chepachet RI not long ago they had a 65 up on a stand. What a neat looking little bike. It actually stopped me in my tracks on the way out of the shop and I had to check it out. Give em a call and see if they still have it. 401 567-9300

For a picture look at the Gas Gas USA web site. http://www.gasgas.com/cross65.htm

Hey steve. I have an MC65 '06 for my kid, and I know nickname:'brains' here have one too. We have been mailing quite alot regarding the MC65. We were trying to put together a gasgasrider wiki page on the MC65 but we haven't gotten around to it yet.

The MC65 is a very powerful mini crosser with a very distinct power boost when coming on the pipe.

The engine is definately a pre 2005 derbi engine, six gears. AJP hydraulic clutch. Marzocchi 35mm forks, one leg has compression dampening, the other has rebound.

I'll ask webmaster to open a MiniGasser forum section.

In sweden the prices for new bikes is the same as pumpkins.

Some spare parts are pretty expensive, especially piston/cylinders. But since it's a derbi engine, it should be possible to find substitutes. However I have not found the 65cc metrakit cylinder anywhere in the aftermarket shops, but 70cc cylinder kits are virtually everywhere.

Don't confuse the 50 and 65. They are completely different bikes. The "EC50 boy" is a "TXT Boy 50" trials bike with seats and moto tires. Motors are very similar to a KTM mini adventure, but unique to Gas Gas.

The "MC50" and "MC65" are Gas Gas/Derbi hybrids.

And for fun, there's the "EC50 Rookie" or "SM50 Rookie", whose motors were based on the "TXT80" trials, but in downsized EC frame.

Clear as mud?

Sorry, I am not trying to stir the pot of controversy here. I am just trying
to understand what motors are what.

In the end. My ultimate goal was to try and find a big bore high performance
cylinder and piston for the GasGas SM50. If the TXT80 cylinder and piston
will fit on the SM50 cases or not. And weather the port timing and
compression could be played with to move the power up from a torquey
trials motor to street useable HP motor in the SM50.
My knowledge in this area is so limited. I am trying to learn from you folks
that have already trudged through the mud on the path of enlightenment.
Thank you for all your help and guidance.
Jeff, So. Cal.
