Tiger 1200 Explorer - Tuning
I have received a number of emails asking if I have modified or tuned my Tiger Explorer in any
way. So far my Remus exhaust is the only modification and I have resisted the temptation of
further tuning for a number of reasons.
1. Initially I did not want to invalidate the warranty on my new Explorer. When Triumph returned my bike from
the factory recall in March 2014 they offered to extend the warranty on the engine for a further 12 months,
which was generous, but it means I prefer to keep things standard for longer.
2. The Explorer has a 1215cc engine and weighs 260kgs fuelled up so it is plenty quick enough. I can
provoke the traction control to intervene and keep the front wheel down when the roads are dry. Traction
control intervenes to stop wheel spin when wet so for the first time ever I own a bike that does not need more
BHP. I am not interested in top speed, bikes like the Hayabusa are not for me. In normal riding I can ride
indecently fast without using full throttle or exceeding 6,000 revs. When I ride with other bikes the Explorer
never seems underpowered.
3. My Explorer has perfect fuelling so I do not want to risk upsetting the equilibrium (See charts below)
4. In the UK we have over 12,000 speed cameras and a national speed limit of 70 mph so I'm not sure what I
would use a power increase for.
My thoughts on Tuning the Explorer
I am sure the first modification would be to let more air into the airbox. This should improve immediate throttle
response and worked well on my 955 and 1050 Tigers.
Having made an adapter for my Remus Exhaust the Explorer definitely has a built in restrictor. The exhaust
gases flow out of the catalytic converter through a relatively small 1.75 inch pipe. Look at a KTM 1190 or a
Ducati Multistrada where large 4 inch pipes are used. Triumph probably use the back pressure this creates
to improve low to mid range power. I wonder if Arrow or another brand will make a full replacement system
without a catalytic converter and big bore pipes, I am sure this would increase top end and should improve
fuel economy. However most other Adventure bikes have servo operated exhaust flaps to create back
pressure, the Explorer does not. So I keep thinking would the overall effect be better or worse for everyday
riding? The Multistrada definitely makes more power than the Explorer but only when you go over 6,000 revs
in real world riding how often do you ride above 6,000 revs on a 1200? (6000 = 113mph in 6th). I have
ridden the KTM1190 it has too much power, in "Sport" mode the TC intervenes all the time. Maybe I am
getting too old.
From the charts below you can see that the standard Explorer has a near perfect torque curve with no
dips or peaks, compare it to the GS1200 and the Guzzi. Different charts (not shown) confirm that the new
Ducati Multistrada produces more power but not until the engine exceeds 6,000 revs..
