I've also only had but good experiences with Matt aka DHC. I've even had a slight fitment issue with one of my products purchased (my last build), Matt made the commitment to make a new one that would fit right. Matt came through, fixed the issue, end of story. Pretty top notch to me.

If some haven't understood this yet like stated above. Quality RC51 parts are hard to come by, our bike is old. Therefore if your looking for instant gratification this ain't the bike for you... Just my 2 cents...

I'm sure the weight savings is phenomenal!
What's pictured there is the front, rear, and swingarm axle.

I was going to get the engine hangers made, but didn't have the opportunity provide measurements to Pete in time.

In the next couple days, I will post a direct weight comparison between these and the OEM steel axles. I am anticipating around a ~50% reduction. That is pretty good. In the grand scheme of things though, the axles alone make up only a small percentage of overall weight and even a 50% reduction won't decrease it all that much.

In terms of performance for cost by eliminating some of the largest steel parts for titanium or aluminum, those axles and the triple tree stem are some areas you'll see some of the largest removal of steel from the bike.

But with the so called phenomenal weight savings, comes a phenomenal price (I'll post it later). It really makes no sense to do this in a practical sense, but I enjoy spending impractical amounts of money on this motorcycle. Now all these 500g weight savings here and there from all the unnecessary parts I've been buying will add up and provide a good overall reduction, but at the end of the day it will still be a heavy underpowered motorcycle compared to today's offerings.

I think most people know that, but I just want to make sure everyone understands that I'm not expecting some revolutionary performance increase from what I'm doing. Once installed, these will barely be visible and one could hardly tell a difference. As an enthusiast though, I appreciate everything about it. To me, that's all that matters.

Those Ti bits are super trick! I'm all for dropping weight on the RC and that would be a fairly significant Ti upgrade. Go big or go home right? I didn't see what the damage was on them though. So if I understood it right he can do custom Ti fabrication?

Pete can make nearly anything.

Was able to take some measurements today:

Rear Axle: 343g Ti / 578g oem 41% weight reduction
Swing Arm: 259g Ti / 486g oem 47% weight reduction
Front Axle: 244g Ti / 440g oem 45% weight reduction

657g saved or 1.45 lb

Those parts cost 1115 or $1444.82 at today's exchange rate. So essentially $1k per pound of savings.

The triple clamps came in at 1910g, but my oem triple is packed up right now so no comparison. They cost $1498.

You could buy another motorcycle for the cost of those parts alone that is faster than any RC51, even with an unlimited budget.

I've built a 15 lb road bike and am a bit of a weight weenie by nature. So I am well aware that taking a crap before riding would be just as effective!
