For those who have been waiting for facts and figures without the bullshit. Here is a stock 650 Interceptor and my 650 Interceptor that is fitted with S&S Cycle, Inc. mufflers, pipes from Royal Enfield Sydney / Revelry Cycles, DNA High Performance Filters air filter, and tuned with a PowerTRONIC - Plug-In Performance ECU.

The blue lines are the stock bike. The red lines are my bike.

The tuning was performed by Dave and Vince at Sydney Dyno Pty Ltd

Don't just look at the peak horsepower numbers, look at the improvement in torque and horsepower everywhere. This is a difference that you will definitely notice. It's not a race bike but it is a bucket of fun to ride. Especially with the quickshifter.

Thank you to Will and Santina at Royal Enfield Sydney

interesting figure.

So 3HP gain at WOT with pipes, exhaust, air filter, remap.

How much did all that cost ? I guesstimate around the 1800 USD mark ?

According to powerdynamics their piggy back ecu alone can increase the bhp +3bhp on stock setup with map 2

Thanks HD MIck for doing this and publishing it.
I know that some folks will dismiss "up-tuning" a midsize motorcycle when you could just buy a faster 1150cc something. Then they dismiss the bigger bike because nobody uses all that power ... etc. blah de blah.
That is missing the point entirely. A point that you make and I agree with. Sweet running motorcycles -especially midsize ones - are a real joy to ride. My bike has gone from a really great bike to a _ I love this freak'n motorcycle!

Something to think about.

Where does your tacho needle spend most of the time while you are riding?

That’s the area to look at on the graph I shared.

The greatest gains are right there where you do most of your riding.

I can’t make any comment on that as I fitted the Powertronics unit after de-restricting the intake and exhaust.

Will from Royal Enfield Sydney loaded maps in that he had prepared earlier. They worked well and provided an excellent baseline for Dave and Vince to tune from.

Thanks for sharing these results,  I'm  impressed  how the gains are spread throughout the range. Big improvment at 5500 rpm  , my fun zone 5-6 k

With great power, comes great responsibility.

Use it for good, not evil!

I tend to be a pragmatic. I bought a 6500€, 47HP bike. Because i liked its overall look, feel and engine. It just happened to be a royal enfield.

For the money of getting that same bike up to 50HP (and getting it not street legal in the process), i would buy a triumph street twin in a heartbeat. It has more displacement, a 65HP engine, better suspensions, better finish.

Do not get me wrong, I like my interceptor, and it is totally worth its cost. I just find hard to justify spending that kind of money on an engine to get so little in return.

I have nothing against people doing it anyway. Not everyone cares about the money side when passions shows its head. I am doing the same with my race car (although with VERY different result. OEM power: 171HP. current: 600ish. And it revs higher than my int. Turbos are great  8)) And just like it, it IS a serious money pit !

It was interesting for me to see what the stock curves were like. The HP and torque really follow each other in a linear fashion unlike most charts I have seen on other engines before. The first time I tried to run it to redline I hit a very "hard" rev limiter before the redline began which mirrors what the dyno chart shows. I guess that is the same for all of these bikes with stock electronics. I don't know if it is an ignition cutout or a fuel injection shut down, but it is very abrupt. My last bike was a 1988 CBR250R with 18k redline and was an audio concert of large proportions.

Great to have an informed, sceptical voice on the forum. Really rare and valuable knowledge.

I probably would be more attached to RE (and not sure about the recent gearbox stories around Triumphs) and I tend to be happy enough with whatever compromise that brings. I agree that chasing performance on this unit is more about fun than practicality, but to each his or her own.
