i have an li 125 casing and varitronic ignition so far,
not sure on what gears to run someone mention'd sx150 gearing.
can someone give me the pro's and con's on the above kits?
and also what crank and gearing please

or mentioned it in a "whatever you do, don't use an SX150 box" kind of way

mugello ?
proven kit, with many people using them reliably, and much experience around gearing, pipes, jetting etc.
with a MEC crank

what is fast touring ? what kind of speeds do you want to be travelling at for continuous periods ?

Untouched Muggy 186. LI150 Box, 30mm Dellorto, JL3 or PM pipe = flyer!

I'd love to give the RB20 a crack. That's next on the hitlist

Lee, ive just helped a mate put one of the new muggy 186,s together, and IMO it would have benifited him to have some extra meat welded on the transfers on the caseing, both for some extra gaskit face and/or to open up the transfers some more, while your thinking about which kit to go for if i were you i,d get the caseing welded, my choice would be the RB20, seems good value ;) .
