The handle bar bolts on my 2021 Spyder RTL are longer than on my 2018. What size are they and SAE or Metric?

There are NO SAE fastners on Spyders. None. All are metric.

Unlike Harley that uses an infuriating mix of both.

the handle bar bolts are 8mm. allen bolts. And they are REALLY tight!

[knobby]

I believe they are actually 10mm (thread size)

If you can get one out, take it to a hardware store that has the free to use thread gauges in the nut and bolt aisle. I know Menards has them for customers to test thread gauge and pitch.

They are M10 x 1.5, and not really all that tight on my 2021 RTL, but do have a locking compound on them. I replaced one with a long stud and coupling nut with about 1/2 of the hex cut down on my lathe, then mounted it (with blue locktite) in place of one with a RAM ball screwed in it. Worked great to mount my GPS.
