I own a 1997 Suzuki GN 125 motorcycle. The carburetor I bought is very good. It fulfills its purpose and is solidly made. With the installation I did not have any problems. After changing the carburetor for a new one, the motorcycle rides like a dream.

This cylinder head is perfectly compatible with the 4-stroke 125 cm³ engine of the Suzuki GN 125 and its variants (GS 125, DR 125 depending on year and model).

If you're looking for a high-performance, long-lasting cylinder head, this model is an excellent investment.
The product made very well and solidly. I recommend as much as possible !!! ;)
The only but-> In one footstool forgot to ream one of the two holes, already by eye you could see by the diameter of both that the upper one on the left footstool is smaller. But it's a small detail, reamed 5 min and after a shout.
PS: These footrests also fit Hyosung XRX 125 because I put them on it ;)

With the installation there were no problems rings went nicely into the grooves, the crank-piston pin also fits perfectly. The engine runs normally after the repair, with no disturbing signs.
Price, delivery everything OK. Unfortunately my customer says that the arms of the pegs do not really fit on his GN125. He only fitted the actual pegs and threw the arms away, what a pity. So I had no opportunity to check this statement.
