top spec cylinders comparison!

[yosi199]

Hi, i'm new here. Just bought a Derbi senda DRD 03 model whice have a 1 ring aluminum athena cylinder in it, 17,5mm carb, and a Leo VInce exaust.

it's working pretty good but I want to make it stronger and as much closer to a 125 2t motorcycle.
I was wondering will I feel a hugh diffrence if I buy a racing cylinder?
Is the racing cylinder and parts are more high maintnence than a motocross engine? will I have to do the top end more often than a MX engine?

whice cylinder will give me the most power?
Hebo manston pata negara?
Malossi MHR team?
Bidalot racing?

thanks for your replys!

I like MHR Team best.

My main use of the bike will be offroad riding and dont know if I need a revvy engine or one that have more lower end power and which setup can you advise?

get a 2Fast 78cc/86cc or an MHR Big Bore 86cc if you want something close to a 44hp 125cc 2T dirtbike, you'll be spending a small fortune just to get these cylinders near 30hp & a lot of effort to boot.

If you want the BB or the 2fast kit,you have to mod them! Because these are scooter kits.

The MHR Team 50mm is a very good cylinder allround. The Bidalot Racing and the Pata Negra will give you more hp if you set it up correctly,but not as much on lower revs as Team. For Offrad drving i woudnt bother with either of them. Go for a good Midrace kit like the MK SP or MHR Replica. Will be much better to drive in the woods with.

I currently have athena racing cylinder 70cc 1 ring alu kit in it. will there be any change if i will switch to mk sp?

what about the polini 80cc kit? seems like a good choice for upgrade?
