Katuki Build- SV650 motor in KTM Adventure

Why? That might be your first question. The LC8 motor is a fabulous unit designed specifically for the task. I like it. I looked at purchasing a nice used 950 Adventure, but the size and heft was overwhelming for me--five eight, 150 lbs, 31" inseam, 66 years old. If (when) I drop it, I'd have to leave it.
So I looked at the 690 KTM. Nice. Scarce. Expensive. But I didn't want a single. I already have a 2012 KTM 500 set-up for dual sport and it's great. I wanted a twin for more highway use than the 500 would tolerate.
The Suzuki SV650 is a great little twin, the power (70hp, 47 ft lbs torque) made it a good candidate for an Adventure bike. The Wee-Strom is such a bike, but heavier than I'd like.
Besides, I needed a project.
But mostly, I'm a guy, and when you're a guy, it doesn't have to make sense.

I've done stupid stuff before. Yamaha YZ450 motor in an R6 chassis.

So I started getting parts together with the hope of building some thing as light as I could without getting crazy and expensive. No titanium bolts. I checked it on paper, then with a scale mockup.
As discussed in another post, I'd like to rotate the motor back about ten degrees. That may not be necessary, five degrees may work. So, this project is officially underway.

I found a clean-titled 2005 950 Adventure frame that had already traveled fifty-thousand miles and made a loop around Mexico/Central America. I scraped, brushed and Gunk'd it. Then I held my breath and started cutting off extra tabs specific to the Adventure, to clean it up and so my 990 SM-T tank would fit.

this looks like it's going to be a good one.

Got any Video of the 450 in action?

Great choice of frame and motor for this project.

Weighed some parts today. The frame isn't light, 24 pounds. Incredibly stout, like it could survive a roll down a mountain. I'm sure many have.

The forks arrived from a dismantler in Canada. I took a chance on buying salvage forks off a 2008 990 Super Duke because they were cheap. Luckily, they fit fine after removing the steering wheel lock bracket from the frame. The problem with them is short travel, 5.3 inches, and the street orientation. I'm taking them by MotoLab in Phoenix to see if we can get another inch or more of travel. The parts fiche shows a spacer, so that may work. Besides, I could use the longer length to increase the trail, since a preliminary check showed a bit shallow rake. The good news is it looks like I am fine using a 19 inch front wheel, as the bottom-out distance axle-to-head is 14 inches. A 21 inch might even work, but I'm going nineteen.

The SV650 radiator will fit, but is too wide to fit the gas tank. I checked into getting it narrowed-up, but Myler's said they can remove tubes but not shorten them. So that means I could shorten the KTM radiator, so all good, if it works.

While I was wrapping up for the day, the motor arrived from Colorado, nicely boxed up. I'll get it open tomorrow, test the fit, and see if this project is gonna fly.
