Hello,

I ordered a 2016 Africa Twin at the Toronto Motorcycle Show about a month
ago and the delivery is supposed to be late June or July 2016. I'm wondering if anybody has heard of someone putting a full exhaust on the Africa Twin and
doing a dyno tune on one. I'm wondering if this engine is detuned to meet EU
A2 license requirements and if so what kind of horsepower and torque it can make with a sharpened tune. I'm sure it will be fine the way it is but I would like to see what I can get out of it with Dyno Jet type tuner and a better exhaust like the Termignoni complete system with no cat. Could be interesting....and fun.
I currently ride an 07 CBR1000RR with 170 hp. so I thought 94 hp. with 500+
lbs of weight might be a bit docile, but probably very appropriate for it's purpose.

I'm expecting ECU reflashes will be forthcoming as will FI tuning kits. I'm not in a hurry though, I can pretty much keep up or go faster than any bike I've encountered so far on twisty back roads, including 180hp Super Dukes. The bike really handles well and while it only makes 90-odd hp, you can put all of them to good use.

That's great to know, I can't wait to get mine. I just bought a 4k Go Pro type camera to film some of the trips and off road adventures. My buddy and I both bought the bikes at the Toronto Motorcycle Show. I'm really impressed with the off road capabilities of this bike and it sounds like it's a very comfortable bike too. I doubt whether I'll do that much off road riding, but it will be great when I come to a dirt road and I can ride on it instead of turning around. We both bought the DCT models mainly because of how great they are when you're off road. I think there's a lot to be said for the additional focus you can put on steering and riding the bike without worrying about shifting or stalling the bike on a hill.
Can't wait...............

Mine's a DCT too. The biggest surprise for me is just how good a road bike it is, especially strafing twisties. You'll love it.

True Ad Venture,

Thanks, I'm really looking forward to riding it. Should be a lot of fun with the DCT, it will be fabulous when riding dirt roads on the pegs,...... you're still able shift gears. I'm hoping I can get a bit more torque and HP with a full exhaust and dyno tune. I'm sure it's fine just the way it is, but I loved the sound of the AT with the full Termignoni system on it. With a full system like that increasing it's breathing I'm sure it will need a little more fuel which will add a bit more power. How much, who knows? I keep watching to see if anybody tries an exhaust and tune to see what happens.....{

For what it's worth...I've just stepped off a 2014 Hyperstrada that has the same power and torque figures as the AT.

I've only travelled 840 klms on the AT but about 80 of these have been in the twisties. I found that I was travelling at about the same pace as I was on the Duc....greatest limitation is tyre grip....especially at the front. My sense is that the front tyre is not bighting in as hard as you would want (this is an easy fix). But it is easy to string together a series of corners. The bike simply goes where you look.

My AT was not purchased to race but to do lots of miles and over some of those back roads we get here in Australia....none the less the AT is pretty capable in most areas (in my view) and look at the video 'The Crumble' posted he also tells a very similar story.

I have seen some after market exhausts...they show torque improvements of 5% and if you got that in power by flashing the ecu, would the cost be justified? It's real easy to spend a lot of money for little in the way of usable power.... I'd rather spend the dollars on a better helmet and bags. Most of us...and especially me...will never see the bike real limits...but it will be fun exploring!!

Hi Aussie Twin,

I agree, and you're absolutely right. What I had really intended on doing is using my hydraulic tube bender to make a custom stainless steel exhaust and muffler. All the parts are available to make the muffler and they're really not rocket science and ridiculously overpriced. I bought the tube bender to make the roll cage and headers for my race car, so I thought I would make a full race exhaust for it which I would get lots of enjoyment from, especially at the price..I'm also thinking about making some 4130 Cr/Mo crash bars with the bender, as well. I'll get lot's enjoyment out of that aspect of owning the Africa Twin, as well.
I agree, it's not going to be a race bike but I love the sound of the Termignoni system on the bike, but I'm not interested in paying $2500.-$3000. for one, so I'll just make a set by basically copying one. I can use the stock exhaust for the fit......

Should be fun

Along these same performance lines, has anyone taken the AT to the drag strip yet? I always take every bike I've owned to the drag strip just for cheap Wednesday night entertainment. I know it's not meant for it but I'm curious nonetheless as to what the AT might do there.

Lowcruzr,

Which track will you go to. Come to Cayuga and we can race...lol. You strap down the
front end and put lowering links on the rear suspension and you can launch it without wheeling,
Makes a huge difference to your e.t. I saw a stock R6 go 9's by using this method and
without it....11's. Is yours a DCT or a manual transmission bike....

I have ordered a full Termignoni race system for my Africa Twin which is due to be fitted at the end of April when the first batch come into the country.

They were due last week but there has been a quality control issue with the downpipes and they are delayed whilst Termignoni resolve the issues they are having

There is no Dynojet Power commander for the CRF at the moment but I have spoken to Frank Wrathall at Dynojet UK and once my full system is in the country I am taking my bike up to FW Developments in Preston and leave it with them for a few days.

They are going to design a prototype Power Commander around my bike and then do fuel maps for the standard system, A map for the standard headers with a Termi mufffler and then one for the Termi full system.

I would imagine that the CRF is running pretty lean to get 50-60 mpg so we will see what difference a power-commander and a full system will make.

All the best

Simon

I will update with Dyno Graphs when the work has been done.

It's not quite clear from this blurb released by Termignoni, but suggests no alteration is needed with the full system. Personally, I'd like to have my fuelling checked just to be on the safe side.

To satisfy the requests of high performance from the owner of the new Africa Twin CRF1000L, are now available the racing collectors developed by Termignoni in collaboration with Honda. Made in stainless steel they can be easily fitted on the bike associated to the silencer previously presented and is not needed any modification to the ECU. In terms of weight the collectors are one Kilo lighter (2 kilos instead of 3) but the most important thing is given by the engine performance. The combination collectors + silencer offers a very important increase of power (+ 4.08 hp at 7.570 rpm) and torque (+ 5,28 Nm at 3.000 rpm) in most of the working range.

That's great if that's the case.

I wonder what Arrow has to say as that's the one I'd likely get to use with my Remus.

I cant help wonder if there is anything to be gained out of removing the CAT with a slip on fitted ? Does the temi headers / race pipe have a CAT

Getting rid of the cat definitely makes a power difference on most bikes. Big gain on my S10 when I switched to the arrow headers.

I removed the cat on my HP2 enduro and had to put in a wilbers piggy back chip to get more fuel in , also running so lean before that terminal damage was doing to happen .. made a HUGE difference once it got the fuel ratio right . (need to get the goodies for mapping mod before we can try this )

The Termi full system does not have any Catalytic converter fitted so this should, with the increase in the bore of the headers increase the flow of gasses out of the exhaust.

I would imagine that the bike would then run extremely lean and lead to pinking at best, valve damage at its worst which is why I am having the Power Commander put on the bike at the same time.

I am sure the bike will give out a few more horses but not sure how many.

I will be pleased with 100bhp and a stack load more torque as I am coming off a Multistrada 1200 and onto the Africa Twin.

Yes, old trick, however, I saw a guy have a strap break mid track and pop his front end up. He left in an ambulance. I'm not looking to make it any faster than it is. I always run my bikes bone stock, sans lowering, exhaust, intakes, etc. I just like the fun of being at the track with good people.

I wasn't fast enough to order one here so I'll be waiting for quite some time at this point. I'm still up in the air about which trans to get. I don't think I'm ready for modern technology. :grin2:
