95-108 hp??

What are the differences in the two....Does anyone know what parts are used to reduce the amount power?

And can it be reversed?

The difference between the two is 13.
Some measure HP at the Crank, and others at the rear wheel.
You can do several performance up grades, all it just takes money.
One very common thing is to change out the stock exhaust to a full unrestricted aftermarket exhaust. Those are not always legal for street use, some slip-ons can help increase the HP and you can play around with mapping/tuning.
For me, I have managed to rack up plenty of speeding violations, with my Stripel right out of the box, so.............

You can't have mountains without valleys.

As I understand it from the UK forum they put a bolted on "stop" or limiter on the throttle body cam that shortens the throttle throw to comply with the max crank power output allowed in certain countries (France 100 & Spain 95 I believe). I don't know if there is any related tuning but if so that is easy enough to reverse if you remove the throttle limiter.



Edit: found in the UK accessory catalog, part numbers A9618044, Restrictor Kit 34PS and A9608040, restrictor kit 98PS

Here is a link to the Triumph fitting instructions : http://www.triumphinstructions.com/P...9618044-EN.pdf

No tuning changes, just the throttle limiter

I would be interested to see if anyone has had any progress / success where this is concerned

The specs quote the power at the crank. The stock bike is about 106 - 108 bhp at the crank, with about 10 bhp less when measured at the wheel. THe restriction regs also quote power at the crank.

The 33 bhp restrictor is for EU new full licence holders who are restricted for two years, but the rules change after January making this redundant. A new A2 47 bhp licence comes into effect for some riders, but as bikes can only be restricted by 50% under the new rules and the stock bike is 106 bhp it can't legally be ridden in restricted form on the A2 licence. As well as the 2 year restriction you now have to pass another test to move up a category. If you're over 24 (under the new rules) you can go directly for the unlimited A licence. It was 21 under the old rules.

I think Spain is the only country operating the 95 bhp restriction. Although the rules specify power at the crank, for enforcement purposes bikes are usually measured at the wheel, giving a bit of leeway.

I suspect that the OP is just confusing power at the crank with power at the wheel.
