Honda CR 300 X could it be coming?

Its release date will probably be announced soon, April 1st
 
I would love to be proved wrong though Tim, a fully road legal DP bike with this engine would be great.

Lighter than my KLX 150 but about 4 times the power

the CBR300 has exactely the same engine/piston as the CRF250..is stroked to 286cc and the mod works.done in CM for 15K

That's about right Colin. They haven't even managed to get the CBR 300 engine into the CRF yet so I won't be holding my breath.

@Forrest
I have seen a lot about the possibility but if there's a good reliable place to get it done for 15k I will seriously think about it.
Who and where?
Ta, Tim
 
I'm going up to CM with my bike next month to get it done. There's a few places, I'm using Tium.

Hi Folks
Thanks, any chance of some more info - where, what is involved etc. I am sure there is a lot of interest out there, would be a good basis for a post.

Hi Craig.
Thanks, where is the 'MX Motoshop'? Is it the one that used to be next to 'Riders'? Phil didn't know where they had moved to. You mentioned 'a few places'. What is being done elsewhere?
Ta, Tim.
 
Thanks 'Livin' but I seem to be barred from FB, just keep getting a msg about cookies not being enabled - when they are!
So any chance of a street name or even better, co-ords?

Thanks Craig. I'll take a ride out in that direction when I get over next month. Who knows - might be able to access FB by then also!

I'm taking my bike in to Tium on the 17th October, he's said 2 days work. Drop me a line around that time and I'll let you know details.

I see a foreign guy riding a CB300F most mornings on my ride to work. It looks a lot peppier than my CRF250L.
 
Hi Craig
Then get the API stand alone ECU .
With the FMF and your Airfilter mods even with the 300 ECU you need a fuel controler and your EJK can not handle the amount of Gasoline for 300 cc .
API has the Maps for 300 cc and further adjustment is easy .
Maybe you can cut a deal with them to translate the manual correct.;);)
 
I've been in contact with Randy the Dobek Performance rep for SE Asia, he will reprogramme my EJK for free. Then it will be set for the 305cc Big Bore Kit.

Any advice on where to get the API controller if I decide to go down that route? Their website isn't showing any controllers for the larger Honda bikes apart from the CBR250.

Thanks Klaus.

NOTE : u can also check with LOw Rider shop for mods. look up Monkey Father on FB
for the FBless ones his email is akanploy@gmail.com

Hi Craig

Its the API ECU for the CBR250 but that don't matter , Hardware is anyway Honda or API the same for all 3 models .
Just the mapping is different .

Big different in the API is everthing is ajustable .
Ignition Map and Injection , actually 2 different maps selectable via a Handlebar switch (Power and Eco as example)
Changeing the Ignition timming is key to a snappier Engine , the stock ECU's are to retarded for low emissions .
Idle speed is easy ajustable , cold and hot start ,so as Temperature warning , and Fan trigger point and much more.
No more blinking MIL , the Software tell you exactly whats wrong and show the Fuel ratio.
So you can see if the Bike is running rich or lean . The software maps all Parameters in a Graphik that you can read .

And no piggy Back Controller on the Fuel injector or wirering in to the original Harness .
Just remove the stock and plug in the API ECU .
Then start the Fun , the mapping and playing with the maps to find the best settings .
 
the limitation on the original ECM honda is 10000rpm..which is plenty.unless u dont want to fry the bike in the long run...still I trust Honda ECM for 300cc .pushing too far will just overheat.
yes API has everything adjustable but it can all turn into a headache to tune and find the correct combination sometime isnt exactely fun... also not huge but.. API 6000bht .original ECM honda 2322bht
last ... we are slightly off topic on this... :hijacked:

Does anyone know if the 15,000฿ Up Kit includes the Honda ECU? :OT
Click to expand...

not included! if u dont have a EJK already will need to buy separatly. I am bringing my bike to low rider in morning he will do all for 17k!
 
I'm going to get my 250cc EJK reprogrammed for free in BKK before I take my bike up.

Let us know how you get on Sergio, interested to hear your feedback. Steve has said nothing but good things to me about the conversion on his CRF.
 
Just to pass on the info from Low Rider shop.i left my CRF there to do the mod.he dyno tested a few ECM and FI devices and apparently API was nearly 2Hp lower then the original cbr300' s ! Interesting...
And i have no reason not to believe him.passionate guy about his job+make no difference to him what u buy and want to install..so the most cost effective n best choice out there if u only do the 'stroker' kit
Ps: i also asked about big bore kit ,there is some issues i knew already of with overheating etc.. He showed me a cilinder that needed to be redone within 20k km usage...do your math.if u want more ,just buy more bike ;)
 
:eek1:WTF:umm::hmm:confused:

What sense dos it make to compare different ECU's if one off them is not programmable with unknown mapping and the other one
is fully programmable ???????????????????????????????????????????

Given that some one knows the exact mapping of the CBR300 ECU and put the exact same mapping in the API ECU
both ECU will produse the same Power on the same Bike . The mapping is the importend Thing here not the Hardware .

If somebody tell me the CBR300 ECU make 2 Horsepower more then the API ECU it tells me only 2 things .
First the mapping in the API ECU was not proper done .
second , the guy don't know what he is talking about .

Sorry , i don't want to make someone bad ,or get sponsored by API , just want to set the technical facts strait .
 
Easy Klaus just passing info of people that ttested a few different ways.no one is tryin to put u down or the Api.although they used instruments and did not go by 'ear'(as apparently u did?) proper mapping is very diffficult as u know..yes the bike is running....but....(?)
..technicaly speaking the 2 devices could be programmed with the same mapping, but perform differently.and be of different quality..
Honda engineers spent lots of time/nrg on that and using instruments quiet far our reach (i think u said the nearest dyno to u was bkk?) so..
i trust n respect that everyone make their choice n enjoy tweaking .

You guys do know this thread was started for CR 300 X a Two Stroke ! 'Not the sad slow heavy CRL250 L 4-Stroke :)
 
Sorry to bother u mudboots.u are a click away from happiness.. ;)
.turns out we are mates chatting about crf mods. Yes we hijacked the thread..already said that...
the crf heavy n blah blah is a great little bike with potential to go RTW .....thing I wouldnt attempt on a 2T CR!

picked it up and on the way home Craig. Interesting mod !! Easily went up to 140! (could probably squeeze it even more ! Haha ) but i am on mountain rds now
:kboom :hijacked:

I am very easy :D but i know how difficult it is to compare 2 ECU if it comes to the Power they make .
And its more about timing for fuel and ignition as for the quality of the Elektronik parts or the instruments
that are used to messure it .
Different Dynos bring different results , Airpressure and temperature on different days change it .
And i know that Honda has for shure more expensive instruments then i do but i also know thats all
the settings there choose are for low emissions and low Fuel consumptions .
Depend that sells on this Type of Bikes.
Not for max. Power , and with all there Instruments and money they can not change the physiks .
We all now the Bikes are jetted to lean in Stock settings .
Therfore why shoud a stock ECU make more Power then any aftermarket ECU where i can free ajust
the Fuel amount and timeing and the ignition timeing ?

I have several Instruments to messure Fuel/Air ratio or Lamda , CO , Co2 and NOX and the EJK , a Takegawa Fuel controller and the API ECU
what is the most flexible and acurat ajustable one .
And i try a Lot , and the most acurat Fuel/Air ratio ( close to the Stock ECU )i get with the API simply depend it has the most Parameters to play with
and the most Power (by Buttometer ) i get from the API .
The EJK and the Takegawa Fuel Controller are way off the perfect fuel/air Ratio in many situations depend they just add some fuel to the Stock ECU setting
butt the flexibility is not good enough .

The EJK with its limited settings is based on some standart Engine or exhoust modifications and can never cover every mod that is posible .
The Stock ECU is optimised for the Stock Engine.
Only a fully programmable ECU can cover all the posible Engine and Exhoust modifications .
But only if it is correct ajust , and there are a lot of Parameters to play with .Just forget to calibrate the TPS and the Map how good it may be is off .
Choose to mild Ignition Timeing and you loose a lot of Power .Same with the Fuel timeing .

So i don't believe thats the CBR300 ECU make the same or more Power as a proper ajust programmable ECU .
Not even on a otherwise Stock Bike .

Just my 5 Cent.
