Zumico GR200. The engine fits perfectly, I had no problems in mounting it to the frame. The engine runs perfectly, smokes from a shot. Fast delivery. Recommended.

Engine received quickly, there was a lot of oil in the box but that's because of the carrier, otherwise the engine is great, I mounted it on my masai greystone 50 and it's really plug and play, you just have to connect the cables. On the other hand, the double-branch gear selector doesn't fit on the masai greystone and neither does the kick, so I kept the ones on the original engine, but otherwise everything fits perfectly. I'm really satisfied with the engine and with Gmoto! I highly recommend it!

Howdy.I purchased a 11 tooth front sprocket from gmoto.I was surprised that I only paid 10 zloty for this product as it is from a decent company.I own a street 50 moped and there were no problems with the sprocket.It fits perfectly on a 428 120 link chain.According to me,the power seems to have increased a bit but the v max has decreased.If we try a bit harder and shoot the clutch we will be able to ride on 1 wheel.I warmly and sincerely salute g moto for their excellent and quality products.

Deglaine

The cooler looks to be of good quality. The only downside is that I'd have liked several types of fasteners, because I'm not sure the two metal lugs will hold up over time. They look like cheap aluminum. And there's no silent block supplied to dampen vibrations a little for the radiator. After that, I'm a handyman, so no worries for me. Assembled in half an hour. Would recommend.

Well look ma times . Will install the engine in a KIKKER 5150 . the current one with the semi-automatic is not my taste . hopefully it has the power of 12 hp as stated in the description .

Quad ATV 110, I do not know from which year but somewhere around 2003-2007 Very good quality product everything fit like the original, there were no problems with installation. After installation the starter finally worked ;) Sorry but I did not take pictures :( I did not have time to do so because the children already wanted to ride the quad

Now my starter is working properly I bought this because I ran out of brushes and I often use the starter through an electric starter to start the engine, as for the price it is worth it and as for the difficulty of assembly I rate 5 stars for a layman in my opinion it is trivial but, as you know, it happens differently Greetings :D

Gmoto's reply Thank you for sharing your opinion. You may have received a product that does not match the description, in which case you should report a return within 15 days. Before purchasing, it is worth verifying the dimensions indicated in the photo. Unfortunately, Asian vehicles do not have specific catalogs, hence differences may appear.

The quality makes a very good impression. Shipping was very fast and everything I ordered was securely packed. Really helpful for installation and removal. For me, 1000 times better for the price than sending the nut off with the hammer and driver.

I own a 2020 Apollo Avenger 125 Quad the sprocket was easy to install and I think it is made of durable material. It looks pretty good for the price, and fits like a glove. The 12 teeth fit perfectly, the chain is not too tight and the quad has better performance.

Moped - Barton Fighter Eco 2020 This is not an oring for 139FMB !!! Too small in diameter and too thin. 139FMB has an ebonite washer with a passage diameter of 20.5 mm. This oring, on the other hand, fits a different washer, with a passage diameter of 17 mm.

All about. Assembly without complaint, but I chose a low-compatible part. My fault. Greetings. The regulator is oki,but it gives very high current. It is about 26.v. I suspect the stator. Goods as described and from your side everything on 5!!!

A very useful tool. It is better to buy such a wrench than to play with self-made ones. Such a wrench is cheap and very convenient and you do not need some super tools, just an ordinary socket wrench (ratchet).
