What i can tell after expirience with Razor I in 2009 and RazorII in 2011 is, that the wear-out is very low. 1Season and i can use all Belt-Pinions for this year to.
I hat some very hard hits into the wall
What i was using in spare were the parts, i told. Sorry, i forgot a heavy hit: Lossing Control while RC-malfunktion, i was crashing in safety-fence, i got the perfekt target, when hit the fence-post with the right side. What i was using was lower arm, Knuckle and the upper eye of the shokabsorber. And not as by Serpent, where the upper Eyes only in a set with other parts can be buyed, you can buy these upper Eyes from Shoks as a spare-part, 4 pieces for low bucks
For the clutch, you can also use the yellow shoe from mugen, it works well.
Sorry for my bad english, i hope you can understand, what i mean.
