This was my major upgrade on my GV125. I can’t recommend this enough. Has greatly improved the performance, especially up hills.

Took out the 125 for a test spin and wow i am absolutely amazed.
I’m amazed at the rev range that it now provides, i can cruise at 2500rpm doing 30mph in gear 5, it actually hits 60mph in gear 3 which is crazy! I can cruise at 70mph at 8000-8500 revs, whilst beforehand I would only be able to just hit 70 at max revs, around 10500 to 11,000rpm. This means i can safely commute to work with the bike running at 7000rpm doing about 60 to 65mph which is fast and means the engine is under a lot less stress!!
Those gains are insane, however, the top speed is even more impressive. I was under the impression that the sprocket kit wouldn’t add power, but just shift the power band instead. Which is actually kinda correct. With the stock bike, I only managed to hit 70, barely 71mph.
With the new kit installed, I managed to hit 80mph today on a motorway. That’s insane! So fast for a 125cc!
Thanks for your amazing customer service, keeping me updated throughout my delivery
And thank you for the sprocket kit, it has sure made me happy this christmas. The bike is wonderful, and the acceleration too omg! It’s crazy! It gets to 0-60 in no time
Absolutely wonderful, would highly recommend this modification, so cheap and the chain is a lovely golden colour. Plus the chain seems a lot thicker than the stock one, so it’ll definitely take a couple thousand more miles than the stock one. I love it!

Upgraded the chain and sprockets on my GV 125 c, to the 520 chain, and what a difference it makes. From pulling away for the first time after fitting the differene was clear. Smoother and faster transference of power to the back wheel through the gears and fourth really does feel like fifth.
Really happy with this feels like a new bike. Cheers Marcel 😛

I have to agree to pretty much all Moustache Man has to say. Not had the chance to hit the motorway yet but was running up hill at 55 in fourth. Previously would have been struggling to sit on 50 uphill, I am bigger than average so it is to the bikes credit that it manages this :p.
Oliver (verified owner) –
After reading the reviews and speaking to Marcel I decided on getting this kit and I’m glad I did. Great quality parts and I have noticed a change in performance. I can now get 90mph out of it, which is crazy for a 125 cruser! It will comfortably ride at 70 all day and acceleration has improved to for safely getting away from idiot drivers haha! Would highly recommend

Hi guys, I’m getting my brand new bike in October, would this chain fit the new 2021 model
Admin Edit = Send us an email for that. This product page applies to Carby GV125. Your bike is “injected” edition, and there will be a separate page for it.
Any products for GV125S Injected will clearly show the thumbnail/icon of the bike next to it 🙂 And there is a category for GV125S Injected here , keep an eye strictly on that link (or bookmark it 🙂 )

the 520 kit does actually work it changes your gear shifting altogether 5th is more like a 6th gear
i have had 70mph out of my aquila gv125 2008 reg and im around 18.5 stone.
of course i in my last review did not think much of the kit but i was in the wrong ( FOR THAT IM TRULY SORRY)
MY CARBS WERE AT FAULT
standard main jets are supposed to be both 87.5 ……………………….MINE WERE 82.5 BOTH
standard pilot jets are supposed to be both 15…………………………..MINE WERE 17.5 BOTH
so after doing the upgrade mentioned on here main jets front 90 and rear 92.5 MAIN JETS
and PILOT JETS 15 and 2 1/2 turns out with the mixture screws PLUS balancing the carbs .
fitting irridium plugs
fitting upgraded ngk plug caps found on here
my bike has gone from doing 55-60 at a push slowly………….TO A VERY FAST PICK UP AND 70MPH AND BELIEVE ME WHEN I SAY ITS FAST ENOUGH….
LASTS WORD GOES OUT TO MARCEL FOREST HE IS TRULY A GOOD GUY .
