General Two Stroke Talk / Expressions of interest: KTM250/300 350cc racing cylinder and 380 race cylinder

« on: April 16, 2013, 08:50:32 AM »

Wanted expressions of interest for the following

1. A GP derived cylinder for the KTM380 which should produce 75RWHP at 9000RPM with the correct pipe and ignition unit.

2. A 78mm big bore MX cylinder for the KTM 250 and 300 models which will take the motor out to 350cc's.
 Expected power will be 55-60hp.

The 380 cylinder is currently being designed by my freind at Ferrari/Maserati in italy and will be ready for testing in a few months.
I am taking orders for this cylinder down on a refundable deposit basis.
Call for pricing

The second cylinder will be an adaption of this cylinder, to fit the modern 250/300 motors with the 72mm stroke.
The ports will be redesigned to boost bottom end and mid range while still yeilding more top end than a 500cc MX bike.
This cylinder is currently being considered but is not in production yet, it will only be done if there are enough interested customers who are willing to put down a refundable deposit (ei: refunded only if the project goes belly up or doesnt work as promised).

So if anyone is interested put you name down or shoot me a PM and I will be in contact once we have enough numbers to consider doing a production run.


time frame for each projects production:

KTM380 race cylinder: 9 months
KTM250/300 (350cc MX) cylinder: 12 months until deliver (approx)

The cost of each will purely depend on demand, but to give you an idea of costs: it will cost me $1000 to rapid sinter cast one KTM380 race cylinder.
But if more than 5 people want one of the 250/300 cylinders we can utilise a large batch production method which will almost halve the production costs, so the savings can be passed onto the customers.

The cylinders can be provided as is, or as a full kit.


Anyhow, let me know if your keen and spread the word.
I should have the first 3D rendered CAD model images in the next month or so.

Very interesting read

Here is the fourth page where the ride test is undertaken and reported on

http://www.cafehusky.com/threads/round-two-of-the-other-carb-types-lectron.29488/page-4

There are 20-odd pages more which I will read over the comming week but from early on this thread suggests the SC and LECTRON perform very similarly

General Two Stroke Talk / some Jotagas 300 information

« on: September 02, 2012, 04:49:33 PM »

Some interesting information on the Jotagas MK 300 enduro bike which is apparently set to be produced in 2013. I have sent an email to the Australian importer to get more info on prices and release dates etc.
Until I hear back this is all I can find:












Their Bimota 300 enduro publicity stunt was a brilliant idea to get a small manufacturer from Europe into the worldwide media

General Two Stroke Talk / KTM MOTORSPORTS INTERVEIW, Q's ON 2T's

« on: July 12, 2012, 09:58:39 AM »

interview with head of KTM motorsport: PIT BEIRER with reference to moto3 racing

The switch from two-stroke engines to four-stroke engines has raised some criticism from riders. For example, Danny Webb said that four-strokes are easier to ride, and this was making it harder for a good rider to make the difference. Are the four-strokes too easy?

PB: You see that in off-road and you see it in roadracing, that four strokes are easier in acceleration, you don’t have this power hole and then a big bump. You have just this nice and consistent acceleration. So once the riders are fully on four-strokes, it will be hard to go back on two-strokes. If they learn to ride a two-stroke, it’s always easy to jump onto a four-stroke. The other way would be difficult.
Four-strokes are the state of the art at the moment, it’s the highest technology. It’s not cheap, it’s expensive. I don’t know if it’s for the good of the sport that we use these highly developed four-stroke engines, but it is like it is, and we want to play the game on the top-level, so we have to do it.

Would you like to go back to racing two-strokes?

PB: It would make sense on the cost side, and you see we still have a really nice two-stroke family within our off-road field, and we see on the demand side, the demand from the customers is still there. But we cannot push now for two-strokes, because they will blame us for changing the history of motorsport, and we want to be in the top classes at the top levels, the FIM makes the rules and we follow them. So we don’t really push in this or that direction. But in KTM, there will always be strong two-strokes and strong four-strokes

General Two Stroke Talk / CRM250 SMR with CR cylinder

« on: March 30, 2012, 08:05:52 AM »

Hey fellas,

While procrastinating about the KTMito, I Got my supermoto race bike fired up on the weekend for the first time.

Heres what I started with

1999 basket case CRM250AR with probably 20hp at the wheel in its state of tune.



rebuilt bottom end
137.5mm rod from a yz490
custom machined crank to accept the wider rod
KTM250SX piston with custom machined oiling holes
2005 CR250 cylinder, transfer ports reshaped, stud holes offsef, spigot machined down, 5mm cylinder spacer. bored to 68.5mm (265cc) and Nikasilled.
CR250 cylinder head, machined to Superkart specs, toroidal shape
stock 05 CR250 expansion chamber for the beast overall spread of power for now untill a custom pipe is made
Vforce 3 reed cage
custom made alloy intake boot
RM250 PWK39mm with TPS
modified flywheel
she drinks 100octane + a few additives with 20:1 AGIP castor/synth

Electronics are taken care of by an ignitech programable ignition unit

chassis:
powdercoated frame
marzochi 45mm shiver forks
rebuilt and resprung CRM showa shock
320mm wave disc
husky SMR 320 disc adapater bracket with 65mm caliper bolt spacing (ala ducati/aprilia)
Aprilia RSV caliper
braided lines
mito wheels
machined down rear disc
CRF rear master cylinder
new plastics and custom designed graphics
BT003 tires


Final issues to be resolved before first trackday:

-a battery to turn the ignition system on as kicking the engine over doesnt quiet produce the minimum 9V to create spark. My 12V 1.3Ah battery turned up today, its about the size of a cigarette packet so will fit nicely, Im going to just wire it up to a handlebar button so that I can only use it for starting the bike as my charging system/capacitor produces more than enough juice to power the bike

-servo motor gremlins, Iv contacted ignitech as Im convinced there is a fault with my programable ignition box because the servo is about as productive as a retarded 3 year old.



final product

General Two Stroke Talk / next years husky rumors

« on: December 09, 2011, 07:56:06 PM »

Iv been hearing things from one of the new husky dealers about the 2013 WR 250/300's which are going to be unveiled in 6 months and in showrooms in 9 months or so.

I was told that these husky's were a 'completely new breed' and would 'make the ktms look like dinosaurs'

was also told to "expect something radical"


Im hoping that this atleast means that the 250/300 motors will be redesigned and put in a more current chassis similar to what the four stroke models have.

I have also been told that a 6 speed tranny and electric start are pretty much confirmed.

and there is a big secret that he wont let go of... I cant get it out of him, Iv tried.


fuel injection? (doubt it but we can always hope)
new WR300SMR model? (would be very cool)
a bigger capacity 2T? (unlikely)
some crazy electronic package? (map switch? likely)
ABS? (good chance)

the abs would be interesting on a motard and the abs work gear set up can bolt onto any disc with a husky bolt pattern.
would make the bike a real weapon in the dirt section of the supermoto track!

I've told the dealer that if the 2013 model is as much of a weapon as he claims it will be, then I will be taking the first one he gets off his hands and arranging finance. It will be converted into a very nice motard, but the bike and full kit would set me back roughly 15k (AUD)

the 2013 model would have to be an absolute stunner to make me buy new instead of picking up a near New TM300 for a few thousand.


any thoughts?
