What year bike is it?
Is it just in second gear?
What engine mode are you in?
Do the revs rise as you open the throttle?
When was it last serviced?
Is the battery good?
Does it rev freely when in neutral?
Where is @me_groovy or @National_Treasure to tell us instantly what’s wrong?
If I was a gambling man I’d wager it to be a combination of the manufacturers reducing emissions and the local authorities introducing reduced 20 mph speed limits. The manufacturers will have us believe the type of issue described here is characteristic of a modern Euro 5 engine with multiple riding and user definable modes. The issue is common with Honda’s range of 1100cc twins and their recommendation is to ride in sport mode, Triumph’s position will no doubt be the same.
Don’t think road speed vs gears, think engine loading vs RPM’s vs road speed. Give it more beans, ride in lower gears longer, change up later and/or slip the clutch on acceleration after throttling off for engine braking.
Sounds a bit odd. Has it always been like this, or is this a change?
Manufacturers do sometimes limit acceleration in specific gears via the ECU, depending on what mode the bike is in to help reduce the chance of you flipping it, but as it’s an older bike with a smaller engine, and it only happens in 2nd, not first as well, I don’t imagine it’s a designed electronic intervention.
Odd! I would take it to a dealer and ask them to run diagnostics on it.
