MZ / MuZ 125 RT 2009 - Motorcycle specifications, reviews

presentation of the 125 RT 2009

a new wind is blowing through the MZ brand as it makes its entry into the 125 market. Far from the rustic 2-stroke engines that are so much a part of MZ's image, the German brand offers its new small roadster a new, modern single-cylinder engine. equipped with twin camshafts and 4 valves, it features liquid cooling and a balancer. It produces 15 hp, perfect for French regulations, and is both smooth and powerful. Unfortunately, the poorly stepped gearbox means you can't take advantage of the engine's health in the last 2 gears. The rigid chassis makes for precise, efficient riding, and you can count on powerful braking - even disconcerting at the rear. The bike is quite classy, and the equipment list is of a high standard. It's just a pity that the seat doesn't lock and you can't store a U underneath.

pièces détachées pour la MZ 125 rt

coco Model 2001

hi, I bought a 2001 MZ 125 RT and I need to repair it. I'm looking for spare parts, in this case the starter freewheel; you have to push it to start it; the starter turns very well; is there a French site for this bike? the bike runs very well but it's no longer sold, so it's a pain to get parts. if someone can give me a French site, that will allow me to get it back on the road. thank you! 06/24/2017 21:57 Rating : 5/5 Respond to coco

rene Model 2005

A very good score for this unusual bike, I'd say 4.5/5, because comfort is a bit hard to find on the saddle, but once you've found it, you can go very far with this real bike. We were able to put it to the test by touring the Massif Central, accompanied by a big cube from Bordeaux, and riding it every day the rest of the time. A beautiful bike, with a torquey, powerful (15hp) liquid-cooled engine, indestructible at any pace. Same performance as a honda 125 cbr -we've had both at one time- and same sturdiness. It's a sure bet, and undoubtedly one of the best 125s ever produced. It's been out of production for about 3 years, which is a shame, but MZ guaranteed the supply of spare parts for 10 years, so you can still buy a used bike with your eyes shut, as there's little to fear from such an acquisition. Reliability is almost flawless, and maintenance is easy thanks to consumables shared with other bikes (BM f650 for the filter), and parts still in the catalog. Motorcycle for the same use as a 250cm3. 05/02/2012 21:19 Rating : 5/5 Respond to rene

Poupette Model 2010

The MZ 125 RT is a little jewel with a hell of a kick and exceptional braking! Easy to handle, light, smooth to ride, with a speedometer and lap counter, it's a real joy to ride. 07/03/2010 19:21 Rating : 5/5 Respond to Poupette

tomweb91 Model 2000

i've been driving it for 2 years now, and it's very pleasant to drive, and above all to adjust it properly and find the right garage
lots of adjustment problems at the beginning, and above all never go to "mtm" in corbeil essonnes, they don't know anything about it and nearly turned me off the brand
fortunately, I then discovered "trophy moto" in villeneuve le roi (94), then "eur ricane bike" in pringy (77)! super mecano, a retro biker's pleasure! 07/17/2009 17:43 Rating : 5/5 Respond to tomweb91

Gilos Model 2000

Motorcycle acquired on release in August 2000. 35,000 km
Minus: finishing problems (kickstand, stained seat, temperamental rev counter, hard-to-find neutral, power plant at 20,000...) but nothing too serious apart from a battery that needs changing on average every three years. Classic maintenance, reliable and fuel-efficient. Looks a little unassuming, could do with a radiator cover and sabot (the seat backrest suits it well)
The plusses: Comfortable even when riding as a duo, a pleasure to ride, you can really angle it safely (Michelin tires recommended) and make full use of its voluntary single for a 4t, an average of 120 on the odometer and a maximum of 135 at the 6th gear bottom (downhill and wind at your back). I'm having trouble changing it despite its age, not enough novelties in this style of moped. The scooter is more under study... Too bad. 06/29/2009 20:12 Rating : 5/5 Respond to Gilos

Havoc Model 2000

Hi there!

Bought this bike six months ago, 47,000 km, 1000 euros. At 50,000 km, I'm very happy with it, it's a good beast, accelerates vigorously, is very comfortable for the displacement (a must, I think), can cover long distances and runs easily at 120 odometer (115 real) and only drops to 90 km/h on steep hills. It's also as frugal as a camel (4L on average)

Shortcomings? It's not very sporty, the sound is neutral, it's a sort of faux trail bike (titmono), the equipment is a bit sparse, the cold idle is erratic (takes a long time to warm up), it doesn't like to sit under water to cool down, the meters aren't waterproof, the wheel bearings seem fragile, the brake discs wear out quickly, and the kickstand also seems to have problems with fragility

Otherwise, for practical motorcycling use, it holds its own against a good number of big bikes, including in terms of comfort and endurance. Quite unique in the 125 world. Worth a try! 10/02/2007 19:50 Rating : 5/5 Respond to Havoc

fortesck78 Model 2000

I've had this bike for two years and I'm still as happy as ever to get on it
it's true that the importer is particularly pitiful (3-month wait for an RT 125 Classic Sport), which is quite a long time. Just a fault with the cylinder head gasket at the start, but otherwise it's a great bike that's hard to get rid of once you've ridden it
the weak point remains the unreliable importer 05/10/2007 19:14 Rating : 5/5 Respond to fortesck78

Grenouille Model 2000

i've had it 15 months. 11,000 kms covered. In the morning, it starts right up. On the road, on the freeway: 120 km/h easy (beyond that, you have to be helped by the wind in your back or the percentage of the slope or the suction of a car or a windscreen)
It's a real joy every time I take it out. It's pretty, easy to handle, comfortable... it's my favorite toy!
Admittedly, it's a bit... small! but it's a real eye-catcher!
The problem is... it never starts up again when hot. I have to push her... She gets on my nerves when she does that, but I don't care... I love my MZ! 07/19/2006 09:14 Rating : 5/5 Respond to Grenouille

GIPI Model 2000

Hi, I have the SX and as on the RT, what happiness this engine but the same pb as the Rt with an anemic 6th, then I made go up a pinion of output of limps of 15 teeth instead of 16 and there it becomes even more pleasant to use more flexible, and the sixth goes up (on the flat) without pb until 110 passed... 06/20/2006 16:03 Rating : 5/5 Respond to GIPI

bilouze Model 2000

great bike! pleasant to ride, very versatile and reliable mechanically. a little light on the freeway, admittedly, as a 125
the only downside is the lack of seriousness and professionalism on the part of the importer, who never respects delivery deadlines... as a result, I'm annoyed and my dealer takes the blame for the others :p 11/17/2005 17:03 Rating : 5/5 Respond to bilouze

uh bought used with 3000 km, the seller assures me it's a good deal .. then I summarize in 3000 km head gasket problem plus battery regulator demareur ... shitty after-sales service importer who made me wait =4 months for a frame ... argh a shame! don't buy stay away I sold it very quickly and now I'm on a kawa 500!

Chris Model 2000

I bought a new gray RT at the beginning of August 2005, and I have only one comment to make: it's a joy to drive
Good performance on all types of road except expressways, where the extension is insufficient (15hp required). But in exchange, the RT makes up for it with a range of up to 400 km between fill-ups. Otherwise, I strongly advise you to invest in a windscreen, which will improve your comfort, the mono's performance and the overall stability at speeds over 90 km/h. 10/07/2005 10:24 Rating : 5/5 Respond to Chris

cornu Model 2000

I've had this bike for a year and a half now, and I've tried out several in the meantime, such as the dealim roadwin, the cbr and the comete, and I can tell you that it's first on the podium. Ideal for the city, a little ride on the French coast, and for my part, I did 300 km with it on the freeway, and I arrived safely without a fright 07/16/2005 16:24 Rating : 5/5 Respond to cornu

JLBX33 Model 2000

Three years already, 18,000 km of urban traffic, no breakdowns, just the 6,000 km maintenance, and a change of brake pads, chain and tires. Still the same pleasure to ride, for a 125 4T with excellent acceleration, roadholding and braking. On main roads, the acceleration margin is just right, but on expressways it's insufficient, with only 15hp. 04/01/2005 13:17 Rating : 5/5 Respond to JLBX33

kiki Model 2000

It's a great bike, it eats up the kilometers without even giving a second thought. I'm 16, and I got this bike because it's one of the least expensive of the road bikes, compared to the HONDA varadero 125 or the HYUOGSUNG comet, which is very nice but less expensive!! it has 22800 kilometers i got it second hand and the only 1 problem so far is the spark plug. it's true that the 6th is a bit too long but i was able to go up to 130kilometres/hours (breaker) of course i was lying on it and in decent condition ! If you've had any problems with it, let me know so I can change it or get ready to have it
thanks in advance and have a nice trip

bikerboy Model 2000

i've been driving an RT since May and I really enjoy driving a machine like this one. It's managed to eat up the 20,000 km I've shared with it over the last 8 months and I have to say it's got definite driving ability. That said, in town it becomes a danger for the license, despite the anemia she had in 6th grade. 01/20/2005 22:24 Rating : 5/5 Respond to bikerboy

joe bar Model 2000

the bike has only one fault: the gearbox, which wastes all the power of the overboosted mono. its strong point is its ability to swallow any bend, even if the suspension lacks a little precision. this doesn't detract from the fact that I've done 7,000 km in 2 months. adio 12/23/2004 15:02 Rating : 5/5 Respond to joe bar
