Funky half-BMX, half-moped looks good and promises much as a cool urban tool for 16/17-year-olds. Shame it’s let down by disappointly feeble performance, iffy Chinese build quality and plasticine componentry.

None to speak of. The Madass is one step up from a Monkey bike. It’s small, cramped and silly. Its suspension is has less springing than a Bic biro and all the damping qualities of an overcooked pancake. Comfortable it isn’t. What it is, however, is a fun toy.

The aircooled, 4-valve single-cylinder four-stroke is old and slightly agricultural and won’t set anybody’s pants on fire. However, to its credit it’s simple, straightforward, fairly durable and, for the most part, idiot proof. Which, come to think of it, is probably what and engine in a machine like this needs to be. Just a shame it’s so slow…

Don’t expect much. We haven’t heard of anything terminal but in our (fairly serious, it has to be said) experience various bits rattled loose, bent or fell off and many of the components seemed to have all the durability of a cheap watch.

The Madass isn’t exactly expensive, but then it isn’t exactly cheap either, is not well made or durable, and the bike isn’t particularly versatile or practical. Which makes it a fairly pricey, brittle toy. Hmmmm. Find a Sachs Madass 125 for sale.

Not a lot, that wouldn’t be in keeping with it’s urban-techno-grunge styling, now would it?. Instead you get the bare minimum (and cheap and nasty it has to be said) speedo and idiot lights; downright nasty switchgear and not a lot else… Headlight looks cool, though…

3 out of 5 So cool but so slow!
14 August 2009 by mvangel

how to start? I started riding because of this bike: I had first bought the bike and then enlisted to the course and eventually passed my license. Or in other words, for some strange reason, I did bought the bike solely because of its looks! Now after 1 year of irregular use, only through the dry days, I can now confirm MCN review: its slow, poor equipment and weak engine. It is however fun and cool. Fun in slow way and cool as in the "matrix" movie. or at least to me it looks like some of its sentinels, with the twin lights above each other. I haven't tried any other bikes, except for a 20 year old Honda Dominator, so can't really compare, but at least breaks are fantastic and do stop the 100kg bike in no time. It doesn't go faster than 80 on normal situation, so for city slaloming its very good! As other reviewers have put it, its the king (or rather prince) in areas with speed limit 40km/h(up to 60km/h) :) Now I am stuck in the dilemma: tweak it maximum performance, or stop now and move up with smth like yamaha MT-03 or kawazaki Z750 or other naked bikes. Would I recommend it? Only if you do like it looks and you have to pass through the 125cc category. Quality has been ok. Nothing wrong so far. Value: cheep but what to do with it is the actual issue. P.S the specs are a bit wrong, power about 9 bhp and only 4 gears.
