Step 1 - Run-in the Tiger then have the "Off-Road" tune installed on the ECU, my Triumph dealer charged £45.  The result
is smoother running and perfect fuelling.  I also noticed that the fuel economy improved dramatically.  I can cruise at 80
mph and get 55-57 mpg (UK).  At a steady 70 the mileage is often over 60 mpg.  A 2,000 rev roll on in top gear shows a
perfect linear delivery as it rips up to and past 120.  I assume the inefficiencies inherent in the eco friendly standard tune
burns more fuel in an effort to produce cleaner exhaust gases.  Thank you California who have convinced the world  that a
big block motor with a Cat giving 18 mpg is cleaner than a 1 Litre motor without a Cat giving 50 mpg.
Tiger 1050 Tuning 1 - Summary and Exhaust options
Comparing Tiger 1050
One weighs 7 Kgs and
looks like a shinny
Dustbin, the other is a
Remus Powercone
Silencer at 2.25 kgs
Step 2 - Fit a Remus Power Cone Silencer.  I ordered mine from Demon Tweaks in the UK.  It is supplied with a short
connecting bend and a bracket for the Tiger 1050.  The Remus fits so easily I had finished within the hour including having
to remove the seat cowl.  The Remus is not too loud.  With the baffle it has been measured at 97 db.  I love the rasp it gives
to the exhaust and my Tiger sounds great under hard acceleration.  Above 70 mph it does not intrude and all I can hear is
wind noise.  At one track day another Triumph with a Remus and no baffle made 99 db on the same noise meter, not bad.
A very neat, unobtrusive set-up.  Fitting a Remus Power Cone would be a good option if you take a pillion as the
standard exhaust can get very hot up near the edge of the pillion seat.  See my link to an excellent Italian site
which shows pictures of many different systems fitted to the Tiger 1050.  My other favourite is the Zard silencer.
Zard also supply a complete system with down pipes, I believe Arrow supply a full system as well
In April 2012 I arranged to have my Tiger 1050 tested on the same Hardcore Racing Dyno I used
for my Tiger 955i, my bike had covered 26,000 miles.  The result was 129.4 bhp (95.1 kw) with
near perfect fueling.  My Remus silencer still had the baffle in place.  To achieve this figure the
changes I have made are
  • Have the Triumph Off Road tune installed
  • Fit a Remus silencer
  • Modify the airbox
  • Remove the Catalytic converter from the exhaust pipe
An increase of 15 bhp over stock is not bad !  On the road and on the track my Tiger feels
better than when it was new.  
For this dyno test we just put the Tiger in 6th gear and had 3 runs up to the rev limiter.  I did
not bother removing the tank to connect to the ignition coils so RPM was not recorded.  The
power graph show a continuous increase in power right up to the rev limiter.  The fuelling is a
little rich at the bottom end.  This could be leaned off for more power but it would make the
engine more harsh and I need a smooth power curve for road use.
