I don't mind losing top speed really. Just something quieter

Good afternoon everyone. Can someone please recommend an exhaust which would suit a malossi 80mhr replica cylinder and a 21mm carb? I currently have a scr corse chrome and I'd prefer something with more power in the lower rpm and with less noise. Any recommendations? Many thanks and sorry for using ...

Good evening all. I hope you have had a good Christmas. I need a bit of help if possible. I'm rebuilding a 2001 derbi senda r and the engine is missing the crankcase bolts. Does anyone know the size? Are they all the same? It's a brown ebe050 motor.
Many thanks

I gave it the first start today and it was very smokey. I'm running 33:1 using e5 fuel and putoline mx9. I'm going to be using this bike for light offorad

Hi all, I've just received a new exhaust for my derbi senda. The exhaust is a gianelli. My setup is a new airsal 70cc cast iron and 21mm carb. Stock airbox. Does anyone run this setup? I'm after an idea on where to start the jetting please? Also, are there any Derbi or moped meets in Northern France...

I do like the Leo Vince. It's hard to get here and expensive

Hi everyone. Hello from the UK. I'm looking at getting a quieter exhaust. I also would like more lower rpm power for off road use. My current setup is the following Airsal 70cc cast iron Scr corse chrome 21mm carb 14 53 gearing 17inch wheels What I'm thinking of doing is Airsal 70cc cast iron 21mm c...

Hello all. I'm used a scr corse chrome on my derbi senda with a 21mm carb and a malossi mhr rep 80cc cylinder. The scr is very loud. Is there a silencer that would fit that would make it alot quieter? Or is there another exhaust I could use?
Many thanks

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?

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

Excellent thank you.

The bike has only 1000 miles on it

Hi guys. Just purchased another derbi. This time a 2017 model. It's fully stock at the moment. I have a scr corse chrome exhaust on the way. Anyone have this setup? What sort of jetting will be needed roughly?
Happy riding!

[*] Hi all. I have purchased a new derbi project. Its a 2017 extreme drd. The reason it is a project is that frame has been damaged beyond repair as it was nearly stolen. I have a spare frame from a 2001 derbi senda r. Will everything fit the older frame? The panels and seat look different on the 20...

Yes that's the bearing I mean. I may just have to leave it

Hi guys. Sorry to use English. I'm just rebuilding my block and I'm wanting to change out the gearbox bearings. What tool do I need to pull the small roller bearing out of the case?
Many thanks and happy riding

I've ordered the scr from maxiscoot. It should be with me mid next week. I'm just waiting on some new gearbox bearings and then I can start the rebuild. Exciting but nervous

My motor should be able to handle it. It's having skf c3 crank bearings with a jasil evo high tech crankshaft. I will get some pictures tomorrow and try and put them up. I may put a post on the project page.

I might get the scr corse chrome. Seems like good value for money. I'm hoping to achieve 100kmh

I do. I just need to see how to put them on here. I bought it as a bare frame. So at the moment it's just a pile of parts. It needs a full motor rebuild too. I have ordered a new crank and bearings. I'm going to do alot of miles on the bike so I'm not looking at anything too high revving. I have see...
