From what i know its tough to get the 690 in a ktm frame. More doable in a polaris outlaw frame. Its really cool how polaris and ktm worked together in the atv department. If ktm would just keep building quads id feel alot better. At the very least it would be nice if ktm followed polaris in the razr domination!! Lets start some movement. There i go bleeding orange
Thanks Brennen. While Nick's 690 is undisputably badass, I'm not sure it's a properly XC-ready bike. Though... If he'd let me, I'd love to run it at Ironman next year! I'll even replace anything I break and I promise not to complain about it's overall Polaris-ness! (says the guy building a nasty Predator in his spare time... )
nick will chime in, only 10lbs more than the xc engine ? and has a 6 speed with legs for a true 100mph easy top end. Apparently the rear shock mount location makes the intake setup tight in the KTM chassis. Quite a few been done in Australia mainly into the IRS chassis, but I do know one into a KTM over there as well. All used for rallye type racing where the big legs really come into there own. Guys there reporting 68 - 72 hp using the KTm Rally cam (like Nick is using) and minimal other mods. Big powerful engine without being overstressed.
the 530 is an easier drop in for sure based on your pictures
The 690 weighed 12 pounds more than the 450 I removed.
And Walt, fat chance you get to race the 690! haha But you are correct, it's not the best XC machine at the moment.
You are correct Craig. The RR cam is something to take seriously. I haven't gotten to 100mph yet, but with some tweaks here and there, you could do it. I'm guessing I'm in the mid 80's range right now simply because I have it geared very low (don't need the top speed).
I'm pretty sure I'd be over the 100mph/160kph with 15f 37r with my big bore 530.I've never clocked it thou... I think the 530 is a few lbs lighter than the xc engine..I had looked into using the 690 engine but was advised against it because of the weight and height...
