The ti frame is made out of grade 9 stress relieved tubing. It has more flex and higher strength then the 4130 does. I ride hard and jump everything in front of me. so far my Ti kit is holding up good. I did some good testing on the welds before welding up the kits. they seem to be strong. Only time will tell.
I know based on specs it should be better it just never worked out like that for us.
As you gain experience with Ti and the relative low power and weight of the MH may be just fine . A little different then a 300 hp 500+ pound sled.

This is relevant.
This thread is single handily effecting the value of tea in China!
Just like duck hunting, only the haves can pull the trigger on the birds that roost in the corporate leased promised lands.
Used ones are bringing the price of much younger Twoskis, only makes cents when there's guys here willing to trade their Pro for any MH kit and a bike.
I wonder if the same recipe would go down well if TS Mountain Tamers tasted the same, there's something to take to market, lotsa sheeple and their fleece is ready for a sheer.

I think there's going to be a run on MP3's...

Why not an Aluminum frame? Significant cost reduction compared to Ti and could still achieve a considerable weight savings. Any thoughts?
I dunno, the green side of me wants to see some more bamboo being used in the kits.

Just saying if you lost 15-25lbs as a rider it would make a much bigger difference than shaving 15 lbs of weight off the back of the bike. Just like skiing or snowboarding the lighter your are on top of the pow the better you will shred and carve. The money it would cost for a titanium kit could probably pay for a personal trainer everyday of the week. Just food for thought.
15 lbs
It is not just the 15 lbs weight loss. Much of the loss is rotating weight from the drive axle and jack shaft which increases power transfer. And more with the belt drive system.
For my $$ I would want the axles, belt drive and leave the chassis alone.

I tried aluminum, it just doesnt have the strength, it was fine for a bit, but the really hard hits, when the suspension would bottom out or almost bottom out ended up slowly bending every thing. so by the time you reinforce and ad braces and gusssets it is just as heavy as steel/chromoly.

If you're using 6061-T6 Aluminum and make a chassis ut of it then that means you MUST heat treat the thing. Which is quite a process : quench, align the frame and then temper it to get it back to the T6 state. Requires an over the size of the chassis that's capable of 900 degrees. Same as if you'd make an aluminum bicycle frame out of 6061-T6. 7000 series Aluminum wouldn't require this kind of treatment but is not that available commercially.
If a guy doesn't do it, it's gonna either snap just besides the welds or slowly bend... and eventually snap somewhere. Unless you're so overbuild you don't even reach the yield point of the heat affected zone.
I'd say 7075-T6 Driveshaft/ Jackshaft would be the ticket for a cheaper upgrade for a lighter product over titanium or steel. Plenty plenty strong, Crazy mountain is using this for their machines. Handling 50, 100 horses is no big deal. Sprockets would of course have to be made different than what we're used to see tough. Splines won't work with aluminum. The alternatives are out there, it's just a matter of making it happen.

Aluminium may be a sensible solution for rotating components especially if you up size them. However it will be a loosing battle to try to make suspension components out of it . There is no real weight savings over Crome molly and it is only sensible in applications with very high production numbers to get the cost down. Suspension components have a great deal of flex and it took the bike industry almost 20 years to get enough flex into Aluminium dirt bike frames to make them competitive to Crome molly. There does not seem to be a weight savings to be had there , as in many cases the european bikes with Crome molly components are lighter than there Aluminum frame counterparts.

but. I'M the guy asking you all of the questions two weeks ago at Peco's the day that you took the guy for a test ride/demo on the Husaburg 570. I Was drom Michigan in the black truck. Do to all the info that I received from the dealetship employee's as well as from you I believe I'm going to pre order a Carbon/Ti kit. I followed your advise and watched YouTube videos. What will the ore season/snow check options be?? Oh, what caused the cogged belt to break, i.e how did ice get into the cover??

No, my kit is a chain and sprocket driven secondary. The Ice issue, with a couple of people, was with Idler sprockets when people do not thaw their kits out after a big day in the pow. Ideally you want to thaw out an ice covered bike after a big ride and perform routine maintenance. Thaw it out, check chain tensions, chain wax, change oil etc. Sometimes that might be hard to do if you are away from home etc... but those maintenance procedures will keep you riding trouble free. The belt drive system is being tested currently. When, and if, it is a dependable and consistent system, we will see more. It is inside the cover and is a great concept at this time. Testing and time will possibly make it a part of future kits.
I made it clear earlier that the Carbon/Ti prototypes are not available as a production unit. They are simply new and exciting new concepts being tested and experimented with at this time. They "may" offer a Titanium kit as a special pre-season order. That decision has not been made yet. We will be sure and advertise if that becomes an option. As of now the prototypes are simply R&D. Thanks

I for one would really like to see how the drive belt works on the mountainhorse. My new polaris with the drive belt is a improvement over the chaincase in previous years in my opinion. But make the belt drive with a tension pully of some sort. Keep on pushing the limit boys!!
Why not the simplest soloution?
I am as of know working on replacing the heavy CrMo frame with tubes of Ultra High Strength steel. I am also working on a design to replace the alu sides on the kit with Ultra high strength steel that are roll formed "here and there" to improve strength in all directions. The frame we already know will be both lighter and stronger. Question is just how much since we are also trying to redesign the frame a bit to get the high stress points more accurate to better hold up. The side panels are a bit more tricky to make lighter, but in any way they will withstand a whole lot more punishment without getting bent. Springback/Recoil in the UHS steel is about 20%, so you can be pretty brutal with it and it will still go back to same position. Superb if you hit a stump/log/stone that is hidden in the pow. Will have it finished incl powdercoating and all til next season. =)
