You can do a twin conversion - calipers are free but you have to use OEM Ducati disk's

did motorapido do a write up on this ?

yes u can convert to twin set up if required...as the fork leg has the option to mount a second disc......

620 come with twin typically 583's have single..its all you really need imho

i did not think callipers were free tony.?.....thought they had to be oem ducati.?........as per discs.?

*phil looks for rules *

LOL

Oh, and we forgot to say ... they are awesome fun :biaggi:

...or not... :lol:

As said calipers are free but you will struggle to better the brembo golds. Fork internals are free and maxton offer a cartridge conversion kit, don't think many have these as they are £300. A linear set of springs and different oil/levels is pretty much good enough.
On the 620's you can also change the base gasket but you have to have custom made ones, not much point really. On both engines careful set up of cam timing and clearances is vital to have the most hp ;)
On the dyno I use the most they have seen is 65hp from a 620 and 55 from a 583 altho that was later toned down to 53 to get some midrange. A well worn engine gives more power. Rebuilding the engine and taking all tolerances out to max gives the same effect as a worn out engine.
A cheap non o ring chain is worth 1-2hp as are ceramic wheel bearings but I doubt anyone runs them at the cost they are.
Rules are strict and tbh the best gains are from weight loss, bike and rider lol
I suppose with little hp then aerodynamics could play a part ? I dunno but it's one of the few things that can be played with as is the airbox but that's a whole other subject ;)

well that's me screwed then... :lol:

You're not alone :(

We weighed all our bikes, the 620mong was 152 kg, the 583ss was 158 and the 620s was 168kg so it is something worth looking at if only to save some fuel lol
