Airfilter box question

[Lokutes]

Hi all

 

Quick question to the experts, does the airfilter box from a gv300s fit on a GV125-S?

 

Thanks

Probably not (not 100% sure yet) , as GV300 has 3 different designs now  (GV300S, GV300SS, GV300R etc…) and I am currently suspicious that the GV300S may be using larger bore throttle bodies  (I haven’t personally taken apart both a GV125-S and GV300-S in my workshop yet  ,   there is more 125s in the UK than there is 300s)

I know 100% that Hyosung is using a newer design air filter now going forward, it is like a flat pancake style filter now.

Why do you ask ?

Hi Marcel

All the after Stock parts fit both gv300s and gv125s, apparently the same just a different engine.

I like the look of the gv300s airfilter box that’s why I asked. Looking at pictures of both they look to have very similar fittings.

You mentioned there’s a newer design? Does it fit the gv125 s? Any pics?

They did the same thing with pre-2017 GV125 and GV250 = Same chassis , same air filter , same coils,  but as GV250 got more improved over the years  , less parts started to fit  GV125 Carb Model   (because after 2008-2010 GV250 started to use EFi parts, and we could not even use EFi parts on the GV125 carb model)

Eg. GV250DR  / GV250DRA = Air filter does not fit at all , it looks the same but they forced it to only fit 2018+ model and only Hyosung makes it.

GV125S/GV300S were identical in 2019-2021 (for plastics and fuel tank) , but as you found out now, due to newer Euro5+ laws passed in the EU, hyosung is doing GV125R . GV125X , GV125-SS EVO (USD forks) ,  they started to change little parts inside there and there even engines have newer casings.     Injectors in GV300S will not even work on GV125-S , etc ….  It starts to get complicated ,    as you go deeper.

So if you wanted to use a GV300S part, it is safer to go for 2018-2020 models  before the 2021/2022 facelift.  GV300-SS (GV300SA) definitely has a different style airbox and i can’t confirm yet it fits GV125-S due to throttle bodies   ( i need to buy a GV300-SS throttle body to verify this )

They are changing  GV125-S / GV300-S  too fast for me to keep up lol.

However, don’t expect any power improvements using GV300S air filters,  blame the stupid emissions laws in EU

This is the recent facelift 300S (SS / EVO )  – There is also an R model in Israel,  looks same as GV125-R in France  (Sima Moto is the main EU importer)

Thanks mate

Not after more power and also not expecting any, just like the look of it 😉

Further studies and testing on my part will be conducted when I can, as i would like to make some mods for those newer models too.

Power on a 125 is something i will work on! – While the EBC clutch upgrade is good (on the shop) better than stock,  I will be trying a carbon plate (yes real carbon from EBC UK) ,  only 1 rider said it is a little improved over EBC HD , he is still testing…

Looks = Beauty is of the beholder haha.    (my eyes prefer the older S look as i loved the older GV models, so a bobber isn’t too bad) , new model USD forks make me worried about chrome rot or stone attacks from road ,   RWU forks are easier to maintain than USD forks.
