Malossi mhr replica 80cc

[Derbir100]

Hi all.
I currently run a malossi mhr rep 80 on my 2018 derbi senda with a 21mm dellorto carb and a scr corse chrome exhaust. Is there a better exhaust that would suit this setup? I can get 65mph maximum using 14 53 gearing.

Many thanks

Do you have the scr corse chrome 50 lower passing or the hm 50/70 chrome upper passing?

I think upgrading to an exhaust that is rated for 80cc (+) would be a step forward. However the upper passing scr corse handmade is a good one for the mhr80.

depends on the look u like too. Voca has a nice 80cc exhaust that goes just like the corse chrome underneath, there is also an 80cc cross version, but both exhaust are around €300 i believe (atleast over here in the netherlands) but anyway, i believe you have the 50/70 version, anyupgrading towards a high reving exhaust would be good for you anyway. a few exapmples are:
-most 70/80
-VOCA racing 80(cross version too)
-SCR corse racing line
-malossi MHR team 80 supermoto
-Bidalot racing factory 80

Hi all. I have the low mount scr corse. The cheapest one. I'm just a bit worried that most of the 80cc exhausts may be high revving exhausts where the mhr rep isn't that high revving. I like either styles. When I change the exhaust will the jets need changing?

Hey derbir, Evert change you make a 2 Troke that has to do with the inlet, carb, cilinder or exhaust needs monitoring of the fuel mixture, in the case of using An 80cc exhaust you'll deffinetly need to retune asbthe enige is less "restricted"
