I might be looking at this used bike. Anything in particular to look for?

Some of them apparently got a batch of faulty crank bearings, but provided the bike has more than 20 hours on it you're likely fine (they all seemed to fail after a few hours).

Listen to the bike at idle. With the clutch in it should be very quiet. Clutch out you'll hear a lot of rattle which is normal.

Otherwise it's normal used bike stuff. I check for bent wheels, make sure the frame isn't bent, etc. Check the airbox... a clean one is a good sign. Ideally I like to remove the whole tail section and peak at the carb inlet to make sure there's no sign of dirt having made its way to the motor.

Pay attention to who rode it. Expert guys can make a year old bike feel like it has 10 on it. They tend to take reasonable care of them mechanically, but they also torture them quite a bit.

When you say Pro 2014 GasGas, are you a where of the 3 models built in 2014?  

TXT Pro,   Racing,   Factory ( previous Raga model )

 

Are you a die hard GasGas buyer? If so the 2014 was the start of GasGas downward financial spiral, My friends 2014 300 racing had torques bit 10 clutch hub ring bolts / my 2014 300 Racing had the 7mm 12 point clutch hub ring bolts.

Both bikes had the fiber clutch plates installed incorrectly and Oh my other friends 2015 Racing 300 fiber plates installed incorrectly OOOPPPPPSy 

 

The installed Brakem Tech master cylinders were manufactured wrong and fail, sometimes as soon as you assemble the bike. The rear master cylinder in my friends bike had metal shavings in it, failed in a few hours. The importer had seen this problem before?

 

Lots of other sniggly problems also like front caliper getting hot and locking the front wheel, just riding down the trail. I have not had a main bearing issue yet.

Clutch finger bent from new, new style 2mm steel plate clutch can not be changed by adding thicker or thinner steel plate to bring the finger height in spec.

 

I have had to through a fist full of hundred dollar bills at mine to make it reliable and work correctly.

 

I recently talked with a large trials dealer and he indicated that no parts were available in the USA from the new GasGas owners? and this brought the price of used GasGas trials bikes down. so this maybe the time to buy?

Side note, yes parts are available from the previous parts importer and from Europe, I have been told that it is somewhat cost prohibitive. Other may have more knowledge of the parts availability

 

As a long time dirt bike enthusiast, I am not a Happy camper with GasGas quality of build on my 2014 and the 2015 is worse from what I have seen.

 

This is my first and last GasGas

Had 2013, 14 and 15 GG 250's, ridden weekly, no problems with any. And it's all my own money.
