Is it just me or is this really good deal?

 

[SauRoNZA]

Well it's the "old" model but if you can live with that it's a pretty sweat deal.

But then I just bought an almost brand new bike with way more technology and a proper 2016 model for about R4k less.

So it all really asks how much do you absolutely want it to be a Triumph?

 

[SauRoNZA]

I suspect that the ECU learns that the temp sensor is wrong (well offset rather) and compensates for it rendering it useless after a while, how long that while is I don't know but I would expect it is not very long. It is after all a closed loop system under constant throttle (feedback from the exhaust will quickly override any ambient temp inputs). Plus, that unit is really only worth R100 max so if I thought it was the way to go I'd make it myself.

Basically, if you're pinging under acceleration the booster will help. Under constant throttle it is useless. In my case I don't think it is pinging yet, but my issues are under constant throttle.

I don't see how the ECU would magically know the sensor is different.

It will take the false data and map accordingly.

Am I correct in assuming the BMW's run open loop in the idle and lower rev range and after that closed loop?

Granted I don't claim to know too much about these as I haven't used it or needed it but I've seen in mentioned enough that it warrants having a look.

Only time I would deviate from the stock map is if I installed full headers.

And I've done the mods enough previously to want to stick to near stock this time and probably do the OEM approved Akrapovic and maybe a K&N filter to save cost down the line.

Ai didn't realize it was an old model... I do like the street triple though. I emailed them asking what deals they have in the street triple just out of curiosity... Not in a position financially to buy a new bike now though.
You have a BMW correct?

 

[SauRoNZA]

Yeah just bought an R1200RS.

I bought my Street Triple instead of a Speed because it just made more sense from a day to day riding perspective.

The Speed isn't really any faster (having out ridden quite a few on RAT runs) while eating more tires, fuel and chains + sprockets in the process.

I sold my Street now at 36000km with original chain and sprockets all in almost unworn condition except a little rust.

Personally I think you only buy the Speed out of ego and bragging rights. That being said the new model is a different beast and I can't compare anything to that not even having seen it yet. It's apparently not much more potent and instead just has more tricks.

Thanks for the info

It doesn't do it magically. It measures the amount of unburnt fuel and other particulates in the exhaust which is directly related to the amount of fuel being given to the engine, and then adjusts the air fuel mixture accordingly. Over time the ECU then learns what this offset is and adjusts even in the open loop. After all, no two sensors are identical and hence there are methods within the ECU to counteract those differences.

Morning guys. Small question, when replacing your chain with a new one, do you have to change the sprockets as well? Reason being my chain is about finished, but the sprockets still look new, it's hardly worn down.... The interweb says change all as in chain and sprockets together, which is a shame to throw away very good condition sprockets cause the chain is finished, but what do you guys say...?

 

[SauRoNZA]

Makes sense but I don't buy the "over time part".

The map should reset pretty much every time the bike starts or at the very least after extended periods of being off.

It doesn't have a "memory" as such for longer periods otherwise it wouldn't need sensors or simply ignore them.

The sensors are there for this very reason after all.

Worst case scenario it starts the next morning with the old sensor data from the night before and over or under compensates until the new sensor data is attained.

I don't know the BMW system at all, but I did extensive work and research on the Buell's systems and it can't all be too far different.

Whether the Booster plug does anything of use I can't say. But in my opinion the logic is sound at least.

Beyond that I'm of the opinion you either do a full remap or leave it as stock and live with the dynamic nature of the beast.

Sucks that they don't just make all these things open and that companies like Power Commander need to exist at all.

The internet generally states this because one will cause more wear on the other.

However in my opinion the new chain will eat the sprockets and not the other way round. So you aren't really losing anything because if you just replace them you pay for it anyway.

So if they really are in a decent condition I say leave them on and replace when required.

It's the other way round that normally is the Problem, where you change sprockets but not the chain.


On a related note always change brake pads when changing discs. That one you don't want to mess around with.

So glad I don't have these problems any more! #shaft4life

It is simply learning the tolerances of each sensor. By introducing the booster plug all you're really doing is introducing a huge tolerance. Whether the ECU will accommodate such a huge change I can't say, but it most certainly does learn over time

XKulcha . have you guys seen these videos ? .

"Extreme test for XKulcha gear


LOOKS WORSE THAN IT IS?: A brave Hein Jonker exposed his soft parts to a testing bike gear test in KZN.

Local motorcyclist protective gear maker XKulcha recently put four of its top products to the ultimate test – with interesting results. "

[SauRoNZA]

Ag all those companies have similar videos and considering the manner it gets tested not much surprise really.

Don't do much for impact protection but if you were going to ride with jeans anyway you can't go wrong.

Also I believe if you do crash in their pants and send them in they send you new ones.

VTR SP1 for me.

But if I had to buy a collectible secondary bike it would rather be an Aprilia RSV Mille Factory in that price range.

Bought a pair , last ride we had two guys came down wearing them and they just walked away , as you say no good for impact but better than normal jeans .

 

[reactor_sa]

Only gear with CE moulded ABS plastic do anything for impact protection, and even then I can't remember how much.

 

[Joeboy69]

I bought jeans by company called Bullit that has a rating of 6. Apparently it will last 6sec if you skid on tar from 100km/h. Hope to never try it!

 

[Zuner]

I've been thinking about getting myself a pair of kevlar jeans, overpants aren't always viable.

Well that's pretty much what X-kulcha is.

Much like Draggin and Bullit.

Most of the big brands like Alpinestars and Icon also started doing them now realizing that people would just wear jeans and forego protection otherwise.

You don't always want to look like an astronaut. And especially on summer.
