The KaTaMaki 650 ADV project (KTM LC4 gets a twin engine swap)

Never even heard about the Versys before you guys mentioned it, but now that I have done some reading this thing seems perfect! Compact inline twin, 650cc, 6 speed, FI, 55-65mpg, 63HP/45ft-lbs, readily available for less than $1k even here in Europe. Now I just have to figure out if this thing will fit, especially since it's left hand output.

On the other hand, you may consider getting an ER6 (naked version of versys with 5+hp), replace forks, swingarm and shock, transfer the exhaust from under the engine to the side for better ground clearance, lighten it here and there and you will end up with a sub 200kgr fully fuelled bike. The versys is 205 fully fuelled.

Of course this is the 'daddy' of this kind of machine....

I'm with you, Ninja 650 motor hands down.

Hey Lucas,

Keep us posted if you go ahead with this. If the KTM 690 Adventure never sees the light of day, there may well be a few people thinking along similar lines. The Kawasaki engine seems a gun option.

Ta,

putting a twin in that chassis could prove difficult... this would widen the bike a fair bit, and you might not have enough room length wise.

Stick to a single.
I'd put a F650 motor in it, or an x-challenge motor if you can find one. They meet all your demands.

I'm scheming on putting a 650 Versys engine in a dirt bike frame. Pretty compact motor, 6 speed FI etc. A fried of mine is scheming on using a 360 twin Honda motor with upgraded suspension,

V twin? Aprillia 550, lightwieght, FI, powerful, reliable.

Shits andn giggles? CR500, ultralight, tons of power, FI? Who cares man.....

Grafting everything onto the Versys or ER-6/Ninja frame might be possible, but I think it will end up being just as much or more work than a swap. I also doubt that it will work together as well as the LC4 chassis. This guy tried it:

I would also like to end up considerably lighter than 200kg. Around 160kg (without fuel) should be doable, apparently the Versys engine weighs around 55kg (to be confirmed). So slightly more than an LC4, but I can save a bit with lighter muffler, fiberglass fairing, rally tank etc. Something like Jaybo has done on his LC4, except for the rear tank I have almost all the parts anyway:






I have a feeling that a 160kg Adv with a 62+ HP twin would be a lot of fun....

The Versys engine seems to be quite compact. I am going to the local Kawi dealer (who happens to be a family friend) and will get some measurement this weekend. Hopefully I'll get in a test ride as well.

I agree the BMW 650 would be the easiest choice. I might still end up doing that if I find a good deal, but but it wouldn't be anything you can't do with a farkled X-Challenge. Touratech rally fairing, front tank, and steel subframe, etc. Could have just gotten this bike on Ebay a few weeks ago, sold for €6k or so:

LukasM,

The Xchallenge engine might not even be such a simple job, remember the head has a vertical design, meaning inlet trajectory doesnt point backwards, but upwards instead. Jeah, I see what you think, you might flip that inlet rubber 180 degrees, but it's still very high built. Hard to fit that in a frame with a central spine imho.




But how about a PAMI tuned 700cc F650 Funduro engine?

How about a new Husaberg FE 570 engine....

It would kick ass.....

Good picture Max! I was not aware how tall it really is with the throttle body attached. Is the 04-07 F650 engine the same?

PAMI would definitely be fun as well, but I don't even want to think about all the €€€€s a 700cc mill from them would cost. And fuel efficiency?

Heard lots of good things about the new Bergs as well, would love to own one when the 2nd hand ones come down in price.

But in the unlikely case that you could find one for sale, why would you put it in a heavy LC4 chassis? It's a race engine, and should be in a race bike. For an adventure bike it doesn't fit with criteria 2, 3, and 4.

[Maurizio]

This will surely fit in the frame and have good performance, but I don't know anything about fuel economy and maintenance...
