That bar has 520mm Infront of the spikes, so yes somewhere in the 450mm range. It's an oval shape and the pic I have with the saw on top the bar tip isn't past the log when vertical. Might post it later but the difference between new C85 and sharpened 35RS is 0.03 seconds when averaged over 3 cuts. It's a great chain but it isn't fast in this wood in its factory shape, but holly crap is it nice to use. Very, very smooth and fantastic to file. It's a shame it's not made in 1.6mm
