== Overview ==
Suzuki GR 650 Tempter











.

The Suzuki Tempter GR650-X was produced in two models, the budget
X model has traditional spoked wheels, a single color paint scheme
and non-adjustable front forks, all out the door for $2,149. The
upgraded D version got a two tone color paint scheme, magi style
wheels and upgraded adjustable front air forks for $2,399. Cycle
Worlds test boasted, For a little over 2 grand you can own a real,
honest-to-gosh, full-size, brand-new undented motorcycle. Today a
low mileage model will run about $1,500  and most well under that
reasonable sum  if you can find them.

But besides the clean retro roadster styling, the GR sported some
interesting innovations under the hood. The engine is a four-stroke
twin, with dual overhead cams on each cylinder, and utilizes a twin
dome combustion chamber first introduced in the 1981 Suzuki GS650
models, which improves combustion efficiency, and added an air swirl
feature to the fuel mixture. Suzuki also made a bold engineering
design with a trick two-stage flywheel, that when under 3,000 RPM
creates added torque  allowing the rider to lug forward in almost
any gear without stalling the motor.

Power is delivered to the rear tire by a traditional chain. No
kickstart option was offered  but the electric start and handlebar
choke adjustment work well. The twin megaphone style exhaust has a
sweet subdued sound, and pleasing swept-back lines.

The bike dry weighs in just shy of 400 pounds, making it very agile
for a cycle with the power of a 650cc engine. Its 3.4 gallon tank
provides a decent distance between fill ups, as the mileage leans
toward the mid 50mpg mark when not driven hard. The seat is pretty
comfortable and relatively low at just under 30 inches, with plenty
of space for a single rider, and decent for two. Under the one-piece
seat is a small tool tray and access to the battery, as well as a
helmet lock on each side of the frame.

The full floater swing arm suspension includes the ability to
adjust the preload from 1 (low) to 5 (high) with the round knob
located under carbs  useful when riding two-up. The single front
disc and rear drum brake provide adequate braking since the bike is
so light for its class. The entire package makes for a nice ride on
a twisty road, banks and turns with ease, and has plenty of power.
The low-end torque makes the bike forgiving in any gear.

Some performance comments rose about the gearing, which is as a bit
low and make the bikes rev high, annoying mostly when cruising at
higher speeds. Changing out the rear sprocket from the stock 38 to a
36-tooth model is a popular modification, along with swapping the
front 15 to a 16-tooth sprocket. The electrical system is another
potential weak spot, with the stock regulator/rectifier unit
somewhat underpowered, so another popular modification is to replace
the unit with a larger more powerful one. My bike came with the rear
sprocket modification already, and in the course of owning it Ive
upgraded the R/R unit, as well as rebuilt the starter motor and
added some aftermarket accessories.

When first introduced the bikes were well received by the motorcycle
press. Cycle World wrote in their favorable review, Youll notice
weve been carefully referring to this as the GR650, a perfectly
good name for this great bikeTempter is a silly name. This is not a
silly motorcycle.
