Living Legend
I've found (after the fact) that Triumph has changed the through hole sizes on different years of R3's.
From inception to late 2007, the hole diameter on the fixture lugs remained constant at 13MM 0.5118". That encompassed my bike ('06 R3 Classic). Sometime after late 2007, Triumph changed the lug hole diameter to 0.2975 (7.5MM).
Additionally, Triumph again changed the diameter on the R3 Touring, to a different size entirely, 0.320 (8MM).
The lug spacing remains constant throughout all the model range. The centerline to centerline distance is mandated by the frame stubs themselves, the lug is a steel forging, welded to the frame stub
Consequently, I'm curious as to what size lug holes are in everyone's bikes. To that end, I'd like everyone to take some twist drills and slip the shank end through their lug holes. The shank end of a twist drill will be the cutting diameter or the swept area of the cutting lips. That will give me a good idea of what diameters Triumph is using and what years the diameters are applied to.
Finally, in the interest of safety, I'm not inclined to offer the reduced diameters of pins for the Paddock Stand. Loading a 700 pound motorcycle on 2 alloy fulcrum points less than 1/2" in diameter is asking for disaster.
It's a simple matter to drill out the smaller diameter using a common 1/2" (13MM) twist drill. The lugs themselves, because they are forged steel are fairly soft and can be easily drilled with a portable drill and a sharp drill bit. There is adequate clearance on both sides of the bike to accomplish this (I fitted up my Classic, floorboards, tip over bars and panniers) with my Dewalt 18 Volt and a 1/2" drill bit and encountered no clearance problems.
I will, however, make the lift saddles available in all pin diameters that I can get from your input on the poll. The lift saddles (for the scissors jack), because of their design, will carry the pins on both the outboard as well as the inboard saddle, whereas the Paddock Stands only carry the pins on the outboard ends. I'm not impressed with the one sided pin arrangement now offered by others. Radial stress is radial stress applied to the lug (and frame stub). A saddle arrangement negates all radial stress and / or sideways thrust.
Finally, I suspect that's the big ***** about the Rivco Center Stand and it's ill fitments. Rivco only offers the fixing bolts in 13MM. While Rivco states that it's center stand fits all models and years (with the exception of the Touring), that isn't entirely true. It will fit if you drill the lugs to 13MM
If you want to, please leave a comment. This has become an involved project.
