MZ MASTIFF 660 (1998 - 2006) Review

Overall ratingNext up: Ride & brakes
The MZ Mastiff is solidly-built and with looks that could launch nuclear missiles, “aggressive” just about sums up the Mastiff. However, it’s a great road bike, easy and huge fun to ride. Perfect pulling power for townies or twisties and tough enough to withstand abuse and the elements. Pleasantly unusual, too. It’s a goodie.
Ride quality & brakesNext up: Engine
With a reasonable seat height, great geometry and good grip, the MZ Mastiff holds the road well, even at crazy lean angles, which it loves. It may look chunky but it’s made for throwing around. The gearbox is strong: use it along with some serious throttle and you really will be laughing. Suspension’s slightly soft but it copes.
EngineNext up: Reliability
Like its Baghira cousins (and a number of other manufacturers’ machines), the MZ Mastiff takes its engine from Yamaha’s XT660 (the carbed version). Tough, reliable and durable, it offers plenty of low down torque for roaring around bends or tearing up rush hour traffic. At higher speeds it wheezes a bit but, for fun or commuting, it’s a perfect old thumper.
Reliability & build qualityNext up: Value
The MZ Mastiff is incredibly tough, plastic body parts by Acerbis, proven engine by Yamaha, WP shock and Marzocchi forks… This is an A-list team effort if ever there was one. The Mastiff’s carefully and brilliantly put together, boasting excellent reliability and quality that puts bigger manufacturers to shame.
Value vs rivalsNext up: Equipment
Whilst the looks put some people off, those who dare get the last laugh. The MZ Mastiff, as its name implies, is a strong, reliable beast which will weather many a storm. It may not hold its value as well as its starrier KTM counterparts but it’s almost as good and costs a lot less to buy. Fuel consumption and insurance make it cheap to run. Find an MZ Mastiff for sale.
The MZ Mastiff's a meaty bugger with an aggressive, bull-bar style front end and twin headlamps (which work rather well). Large, analogue clocks and a basic display of lights make up the dash while wide mirrors work brilliantly. The front brake lacks initial bite but it gets there eventually; the rear’s almost too good. Both have braided lines as standard. The seat’s a bit crippling.

Model history & versions
1998: MZ Mastiff launched as a supermoto alongside the MZ Baghira enduro bike. Together, they helped the marque’s range become more competitive in the market than it had been and, consequently, helped build it a stronger (and, since then, enduring) reputation than it had previously enjoyed.
None, although fellow family member, the MZ Baghira Street Moto, is very similar in spec (bar different tyres, weight, seat height and styling).

Handling on this thing is sublime and the deceptively punchy engine gets you from A to B quicker than any bike I've ridden. I'm talking in the real world here with potholes, rain and traffic, the places my ZX9R faltered. Having been a courier years ago this is the first bike that leaves me grinning from ear to ear in over a decade. It ranks right up there with the RG500, TDR250 and my race tuned ZX9R C1 in the lunacy stakes, as its harmless commuting often turns into bad boy behaviour when the 2nd carb kicks in. The point is its usable and forgiving, as it soaks up speedbumps and ignores our crappy road surfaces, I swear its just as good in the wet too. Switches are problem as are the Grimeca brakes which are a pain to bleed, just get some Brembo master cylinders an life becomes perfect. Parts are hard to get as no proper dealers exist but I always get what I need off ebay or Grahams of Taunton within a day or two. R1 brakes fit straight on as does an R1 front end. Dont do over 50 miles on a motorway or you will regret it, the Mastiff simply isnt made for that but you will ride A and B roads like never before or as long as you can keep your licence. £75/year insurance(Im 42)and 60mpg (turn the idle speed down) and whose laughing at MZ now? Certainly not the guys in your mirrors!
Needed a replacment for my get to work bike a humble c90, as car drivers apeared to be useing me for a slow moving target !also have a bandit 12 for touring etc>looked at the specs/prices of this type of bike-mastiff wins hands down.it,s not a wheelie merchant,but off the line it really flys cheep to run insure and handles very well.Put another way ,look at an xt660 of same year then add wp shock etc to cost.the important thing is its FUN !!! try one and see.
