It could reach a top speed of 227.8 km/h / 141.5 mph. 
 
==Engine==
The engine was a Liquid cooled cooled Four stroke, transverse four cylinder, DOHC, 5 valves per cylinder.. The engine featured a 10.8:1 [[compression ratio]]. 
 
==Drive==
Power was moderated via the Wet, multiple discs, cable operated. 
 
==Chassis==
It came with a 130/60 ZR17 front [[tire]] and a 170/60 ZR17 rear tire. Stopping was achieved via Single 330mm disc 6 piston caliper with ABS in the front and a Single 282mm disc 2 piston caliper in the rear. The front suspension was a  Single sided swingarm variable preload, compression and rebound damping while the rear was equipped with a Monocross variable preload, compression and rebound damping. The GTS1000 / ABS was fitted with a 20 Liters / 5.28 gal fuel tank. The bike weighed just 246.0 kg / 542.3 lbs. The wheelbase was 1495 mm / 58.9 in long.

== Overview ==
 
As the first mass-produced bike
of the modern era with non-telescopic front suspension, the GTS1000 was an
innovative machine that Yamaha hoped would trigger a brave new world of
chassis design. Like the Tesi ID that had been built in tiny numbers by
Bimota, the GTS featured a forkless front end whose theoretical advantage
was that it separated the distinct elements of suspension and steering.
Suspension was handled by a horizontal alloy beam leading from the front
wheel hub to a pivot on the C-shaped aluminum frame. A diagonal shock
linked the two.
 
Steering was accomplished using
the vertical strut that led up from the hub to a telescoping steering box
which took up suspension movement, and was linked to the handlebars. There
was no room for a brake disc on the left, so the GTS was fitted with a
single, central front disc and six-piston caliper with ABS.
 
Power came from [[Yamaha FZR1000|Yamaha's FZR1000]] liquid-cooled and angled-forward cylinders, 20 valves worked by twin overhead camshafts, and capacity of 1002cc. Fuel injection, softer cams, narrower intake ports and reduced compression ratio combined to reduce peak output
from 140bhp to 100bhp at 9000rpm.
The rest of the bike represented Yamaha's attempt to bridge the gap between adrenaline-pumping sportster and long-distance tourer. Its styling was streamlined, although this was a
physically big and heavy machine. Its riding position was more sports than
touring, giving a slight lean forward to near-flat handlebars, plus plenty
of legroom.
 
 
 
 
 
Effortless cruising
 
Straight-line performance was
reasonable, although in comparison with the FRZ, the four-cylinder engine
seemed to have lost more top-end power than it had gained lower down. The
GTS pulled reasonably well from below 3000rpm, and kicked again at 6000rpm,
cruising lazily at 100mph (I6lkm/h) with power in hand for a top speed of
around I40mph (225km/h). But the GTS was uninspiring at high revs, and faded
well before the I0,500rpm redline.
Its suspension system impressed
with its ability to absorb bumps without the steering being affected.
Handling was biased towards stability rather than agility, partly because
there was no fork dive to quicken the steering entering a turn. Its
stability was often welcome, but during slower-speed manoeuvres the GTS
seemed tall and unwieldy. The Yamaha's most impressive braking was done with
the bike banked over into a turn,
 
 
 
Forkless Pioneer - the RADD MC
Yamaha's GTS front suspension
layout had been designed ten years earlier by James Parker, an American bike
enthusiast and engineer whose firm RADD was based in Santa Fe, New Mexico.
Parker developed his idea with a [[Honda XL600]]-based prototype that was tested
by future 500cc world champion Wayne Rainey. This led to a striking Yamaha
FZ750-powered prototype, the RADD MC2, built in 1987 in conjunction
with Motorcyclist magazine and Los Angeles studio GK Design. Yamaha
then bought rights to Parker's design, and contracted the American to help
develop the GTS1000.
 
when its front suspension kept
working in a way that a telescopic system could not approach.
 
There was plenty of outright
stopping power, too, although the ABS system was too sensitive.
Unfortunately several failings,
unrelated to suspension design, limited the GTS1000's appeal as a
sports-tourer. Fuel consumption was poor and the tank range small. The
fairing was narrow, and its screen generated turbulence. Worst of all the
GTS was extremely expensive. Those factors, and the absence of any major
advantage in most situations, resulted in poor sales. The Yamaha's failure
ensured that telescopic forks would dominate motorcycle front suspension for
years to come.
