I have done a lot of reading on this forum and in other places but it's hard to get a definitive answer.
Little bit of history, previous to my Trek with the Gen 4 I had a Giant with a Yamaha PWX @ 80NM.
By all reports the Gen 4 @ 85 NM is meant to be a kick ass motor and I assumed it would feel stronger than my previous Yamaha.
I still have the Giant and it is now ridden my GF, she now thinks she is a cycling goddess and the worst thing is I can't catch her on the flats without making a huge effort.
Weight and aerodynamics aside, I ride 200klms per week, she would be lucky if she did 50klms in a month and when we rode analogue bikes together I needed to constantly wait for her, so it's not fitness.
I have swapped between the 2 bikes a few times but it's a PIA swapping seats around, setting heights and losing your setup trying to get comfortable again.
It would seem from the seat of the pants and GPS that the Yamaha is a couple of kph faster before it hits the limiter at 26-27 kph and secondly the Yamaha delivers full power right up to the cut off.
The Gen 4 on the other hand seems to be tapering off at about 22 kph and by the time I hit 25 kph it's all over red rover.
Speed is measured by GPS on a Bryton 420 and confirmed by my Fenix 6 pro, Purion is telling me near on 28 kph.
This is not a problem so much off road in Tour where I ride most but when I hit Turbo it is really pronounced.
I returned to the LBS to confirm I had the latest software and 85 NM, which they did.
Anyone care to comment on their experience, is the Gen 4 just a mid range engine for punching up steep inclines, because it feels like the closer I get to the limiter the more gutless it gets.
Would a derestriction chip fix my issue, I'm not looking to go way faster than 25 kph, it just feels that the motor is giving up just before I hit that nice cadence/cruising speed on the way from a ride.
