Number one on the list would have to be a 510.
A purpose built mxer/enduro bike, not a converted trail bike .
I had the pleasure of riding one and it was as close to a Maico 490 as it gets. It was super light, handled, stopped and went very well. I have also ridden a Maico with a TT500 motor in it and it was mega heavy in comparison. I liked it so much I am trolling for one atm.

Hi Shaun. I saw one at Farleigh but I reckon its a waste of time and of two good bikes. The Husky does everything a Maico can. Grants' bike is a good thing, I'm still raving about it!

I agree, I have also ridden the 510 and there is no comparison with any 4 stroke of the era, it was fast, vibrated like hell, more than a touch fragile and built off a 2 stroke bottom end and chassis. No bike to compare it to until the YZ400F turned up.

I think as far as race bikes go there are guys out there who are 4 stroke only guys and run into one who knows how to use a 4 stroke to its best and they will go very fast. Big tough blokes with big bikes  ;D

The number 5 KLX/XR from page 4 is a nice combination.
Is that a bike that is used in OZ for VMX meetings?

Here is  klx xl that I did after brian richards tacked togther 5 frames of  which 3 are now complete bikes. The cr tank is great looking but $$$, I used a $25 kx 80 tank

this one cost $1500 to complete, but they do have inherent problems, mostly because the 500 motor is being squeezed into a tight space.

the major problem is carby location... I never  really sorted this out and I ended up with the really long intake which is terrible for top end power, I also just used a standard carby which is far from ideal. that part of the frame needs modifying to get the carby close IMO.

Another issue is they are very front end heavy.(that big donk again..)

The ITC shocks dont work.. unless revalved and resprung .. i used standard KLX shocks with heavier springs and IT front end again with heavier springs.
 

A nice bike to ride though, but slow. Unfortunately I then rode the same 510 husky  like brad did and  i was totally blown away! So i sold this one ($1500) and got a dead (very)510, which has been the most expensive resto i have ever done but thats another story..

So the kxl was a lot of work for not much money, (Part of the fun to do it as cheap as possible!) having access to a tig and lathe is a must. The husky was easy to revive (not a lot of work) just a sh*&tload  of $$$!! talk about killing the vmx budget...

Guess I group the Bergs in as the red headed step child of the Husky 4 strokes, but you are right, fast and fragile and another step forward to where we are today. 4 stroke weapon of choice current RMZ450  ;D

Dont under underestermate the humble TT250 2valve,a few tricks here and there a drop or two of methanol, she makes some 500's go weak at the knees,not to mention most of the smelly 2 strokes. ;D

Just wait till the 320 kit goes in,when you see the yellow side plates watch out !!

I would love a Husky TC510 or a LC4 KTM but can't find or afford one, so I am building my own take on a 4 stroke. YZ250L chassis, XR500 engine, YZ250J tank and seat. Heaps of trick bits and pieces, lots of aluminum with the goal of making it as light as possible

Well done with the YZ, always thought they needed more torque. Yeah there is something very addcitive about 4 stroke special building

Getting close to paint then final assembly. Getting a decent size carby and air box has been my biggest challenge.
Still have to rebuild a engine, I was waiting to see if it all fitted first.
