Oil sight glass on factory CRF450r?

They change oil after evey moto or heat.
And have it all mesured out
If you can ride a factory bike chances arw you should change oil every 2 rides

I agree, which is why it seems strange to me- they change oil constantly with precisely measured amounts which would make me think that they have a lot less use for a sight glass than the average consumer whose bike sits for lengths of time before needing the oil changed.

Maybe it saves weight

Risk mitigation....a sight glass is something that could be smashed in a crash which then means loss of oil and potential DNF

This is the aspect I was touching on in my original post where I suggested that maybe they are just running it for SX... will be interesting to see if they continue with it outdoors. These are the guys spending big bucks on making sure that KR94 does not have a DNF, then they go and make a special factory case half that has a smashable sight glass in it when the production case does not.

absolutely, Perhaps they think that where the new sight glass is is less vulnerable.....debatable I know

Maybe it's high strength tempered glass that is actually stronger than the thin cast aluminum around it.
