| Suzuki TS 185 Sierra
| |

| | |
| | |
| | |
| | |
| | |
| | |
| The gap between 125 and 250 dual-purpose machines is a hard one to fill. The
| |
| manufacturer must decide to design his machine to include the best features of
| |
| the 125 (light weight, nimble handling, low cost) along with the desirable
| |
| qualities of a 250 (lots of power and torque). This "in-between" sized
| |
| motorcycle can make an owner very happy if it's been done properly, and Suzuki's
| |
| Sierra fills the bill.
| |
| Starting with the basics of their off-road 125 model, such as the frame,
| |
| Suzuki was off to a good beginning. They needed only to refine here and
| |
| strengthen there so that the once 125 could accept the now more powerful new
| |
| 183cc engine unit. But don't get the wrong idea. The 185 Suzuki may have
| |
| borrowed some items from the smaller 125, but it's an altogether different
| |
| motorcycle to ride and enjoy. It's got a personality all its own.
| |
| The frame, taken from the 125 Duster, has been strengthened and reinforced in
| |
| areas of stress created by the new engine. A single toptube and downtube joined
| |
| at the steering head, while a pair of smaller tubes extend under the engine and
| |
| curl up to join with the toptube. This main frame section is amply cross-braced
| |
| to provide rigidity and prevent flexing. Seat, rear fender and shocks mount to
| |
| the sub frame and swinging arm section. A perforated, stamped steel skid plate
| |
| attaches to the frame for rock protection. Welds left something to be desired,
| |
| but the black finish was applied nicely.
| |
| Suspension chores are carried out in a fine manner. Front forks have ample
| |
| travel and good rebound and damping characteristics, but also feature adjustable
| |
| spring rates for riders of different weight. The cam-type adjusters are located
| |
| in the top of each fork tube, and can be twisted with a screwdriver to allow
| |
| soft, medium or hard settings. It only takes a few minutes to change.
| |
| Rear shocks are surprisingly good for Japanese units, and are five-way
| |
| adjustable. Progressively wound springs are painted black, departing from the
| |
| chrome finish found on most machines.
| |
| The forks do a good job of soaking up the little undulations along a
| |
| backwoods trail, but at the same time they don't get snowed by the huge thud of
| |
| a jump or the crashing blow of a deep hole. Over rippling surfaces the rear
| |
| shocks don't pump up and quit working, and as a result the rear end of the
| |
| machine doesn't hop all over the trail with the rider fighting for control. You
| |
| guide the Sierra, it doesn't guide you.
| |
| Steel rims( 19-inch front. 18-inch rear) might be heavier than comparably
| |
| sized alloy units, but they resist dings more easily and don't clog with mud.
| |
| The wheels on the Sierra come with rim locks and balance weights, something you
| |
| don't find on many din bikes . A nice touch, we think.
| |
| The brakes on our 185 test machine surprised us. The front unit is quite
| |
| small but stopped much belter than we thought it would. The rear unit, too, is
| |
| light weight, yet it really works. So often brakes of this size give problems
| |
| when it's time to slow down. The ones on the Sierra had lots of feel so that the
| |
| rider could descend a steep hill without locking the wheels, an important asset
| |
| on any dirt machine. Also, they allow a rider a margin of safety when riding on
| |
| the street.
| |
| The IRC Trials tires are a good compromise for dual-purpose riding, but are
| |
| more suited to the dirt, like the Sierra. Tread patterns are the same front and
| |
| rear, and the sizes are just right for most riding. Ground clearance with the
| |
| stock tires is an ample 9.5 inches, the lowest point being the rear brake pedal
| |
| where it wraps under the right fooipeg.
| |
| A study of Suzuki models, both street and dirt. will show that many items
| |
| follow no set pattern on the machines. For example, the ignition switch on some
| |
| models mounts between the instruments in a convenient location. Other models
| |
| have the switch sitting under the tank on the left side, where the rider must
| |
| hunt to find it and where it is also more apt to collect-debris in off-road
| |
| maneuvers. This is true of the Sierra's also. Another item of non-conformity is
| |
| the fuel petcocks. Some are the conventional off-on-reserve jobs, while others
| |
| are the diaphragm-controlled type that tend to be confusing. The Sierra uses the
| |
| standard valve, without the prime-position.
| |
| Finally, fenders on the off-road machines differ from model to model. One
| |
| will use thin-gauge steel (the Sierra does), and another will use the far
| |
| superior polyurethane plastic. There seems to be no rhyme or reason for the
| |
| modet-to-model differences. Strange.
| |
| Suzuki's I85 Sierra does follow normal practices with its engine unit,
| |
| however, it's quite similar to the one found on the smaller 125 Duster. The
| |
| piston-port two-stroke single is simple and compact, with an emphasis on
| |
| "narrow".- The unit produces 17.5 horsepower at 7000 rpm and has a torque rating
| |
| of 13.5 lb.-ft. at 6000 rpm. which is a fair amount of power for a bike as light
| |
| as the Sierra. The power-to-weight ratio is impressive. Roller bearings support
| |
| the crankshaft while needle bearingsare used at the big and small ends of the
| |
| connecting rod. Even though many of the components appear to be similar or
| |
| identical to the ones found on the 125 Duster, it's not necessarily so.
| |
| Crankcases are strengthened and reinforced to a higher degree, and the
| |
| five-speed gearbox is more robust. Even the clutch has been beefed up.
| |
| More than adequate cooling is provided by virtue of very large cylinder and
| |
| head finning, always appreciated on a hard, day-long ride. Also worthy of note
| |
| are the rubber intent fitted to the cylinder fins that effectively reduce
| |
| mechanical noise emanating from the engine's internals. Manufacturers are
| |
| becoming more noiseconscious day by day and little items like the inserts
| |
| reflect this.
| |
| A 24mm Mikuni carburetor draws lis air through a polyurethane filter element,
| |
| which unfortunately is very difficult to service. To get at the filter you must
| |
| first remove the oil lank and fuss with things you shouldn't have to fuss with
| |
| to clean the air filter. A machine ridden on dusty terrain may require several
| |
| filter cleanings in a day: to have to go through all the motions that you have
| |
| to go through on the Sierra just to clean an air filter, is ridiculous. At least
| |
| it's a foam element and not the paper type. That would be worse yet.
| |
| The 185 Suzuki has a primary kicksian feature, which allows the rider to
| |
| start the bike in any gear simply by pulling in the clutch and giving the
| |
| starter lever a tick. While the gearbox on our machine shifted without a snag,
| |
| neutral was impossible to find when the engine was running. We don't think it
| |
| was simply a fault with our particular bike: we've found that it's a common
| |
| problem with many of Suzuki's dirt models.
| |
| The exhaust system on the Sierra is mounted high and well tucked in so as not
| |
| to interfere with the rider's movements. It's well silenced, and even contains a
| |
| spark arrestor unit, a great item to have in dry areas where there is always a
| |
| fire danger. The rider is protected from the hot pipe by a chromed leg guard,
| |
| which is sufficient to protect a person riding along as a passenger.
| |
| The 185 will make a fine Enduro bike with few changes, and will make an even
| |
| belter just-plain-fun machine for the average rider. It is light at the front
| |
| end to enable you to loft the wheel over ruts or water crossings, yet not tight
| |
| enough to cause looping problems when climbing a steep hill and this one's a
| |
| good hillclimber!
| |
| If sliding corners is your thing, you'll like this little Sierra because it's
| |
| happy in this kind of situation. Responsive is its middle name. It'll jump,
| |
| leap, climb, slide, stop, or meander peacefully at the rider's will. And it'll
| |
| do it without playing tricks on the rider.
| |
| You take that and add it to all the other nice features - like a fat 12,000
| |
| mile/12 month warranty and a low purchase price - and what have you got? You've
| |
| got a pretty darn good motorcycle, that's what you've got!
