Really like this cap. Yes, there is some bling factor but more importantly, it does not leak like the stock cap. Had one on my KTM 300 and now on my 350. Functional bling.

Installed on 2006 KX250

I prefer this much over the stock and it looks a little better. Much easier to remove and install.

Much better than stock.

I've used these filler plugs on every motorcycle I own. They are much more durable than the stock plastic plugs ... and they look pretty nice as well. If you've ever had a rock bash your stock plastic plug, then you'll know how handy these things are!

Looks cool

This is not a mandatory item but it looks good. It stays tight like it should. I have a different brand plug for the trans side and I have issues keeping it snug to the point where I have lost fluid during a ride. This one is the way to go.

Color question?
Does this WC blue cap match the WC blue timing plug set? if the colors are not the same I don't want to purchase it.

Yes the colors should match. Please note that different production runs may vary slightly, but it should not be a very large or noticable difference.

As long as its WC it should match.

Engine ,transmission ,or both?
can i use it for the transmission and engine oil filler plugs on my 2007 crf 250 r

I do know the oil filler cap on some Honda's 4strokes is the same for the Transmission. The easiest way to figure out if that's your case is to try your oil plug on the transmission plug. If it fits than you can order 2 oil filler plugs, one for the oil and the other for transmission.

On my 05 450r it will only work on the engine side. I got a Ride plug for the trans side. Only thing with the ride plug is it will work itself loose. I used a couple drops of blue threadlock to keep it snug.
