That would be around 3000rpm so i guess.. Triumph list the Roadster as making max torque at 2750rpm, however my stock one maxed at 3175rpm but that's a dyno measuring torque at the wheel, not the crank like Triumph.
After fitting the Carpenter engine bits max torque moved up to 6050rpm at the wheel!
Thoughts so far are that the old Rockets' GPS has 6 + N locations
the Roadster GPS has 6 + N positions too
and my understanding of the ECU maps is that they work for fueling by cylinder so no issue, and ignition by gear 1, gear 2 and gears 3-5, so would "hope" that the ignition table for gears 3-5 will also cover 6th.
When my Roadster GPS went funky (happened a few times) and showed a 6th gear on the display, the bike still ran fine, iirc.
When it didn't run so good was when it showed N while in gear.
Guess we won't know for sure until running the engine, but hey we do have Alain for TuneECU (and Chris for Dynojet PCV, for those
@barbagris who like to map by gear

) map modifications, both these guys have been very helpful to me so far.
Correct, the ratios available for 6th were very very limited, however the one which was picked seems to work fine and delivers 80mph at 2180rpm, which by all accounts hits the spot.
Not a darkside anyway
