I have 07 CRF 450r
So I just got tried out my sm around our local kart track with my new RG3 revalved suspension. Springs are rated for my weight, getting about 100mm rider sag in the rear (as recommended by rg3). I also installed 20mm RG3 triple clamp. Front forks are flush with triples.
Overall, bike handles way better than stock trim, stable everywhere in the corner (entry, mid corner and exit). Even switch backs are hard to upset bike.
My only complaint is the slow turning. I rode my bros 09 crf 450 (stock suspension) and it turns like a 250! I was really surprised how well the bike transitioned as well.
I am going to lower the front of the bike 3-5mm. (RG3 tech seconded my suggestion).
Anyone have experience/thoughts on my setup change?
