Love listening to James talk about his bikes :) Really makes you want to buy one!

You said the valves are adjustable as in lock nut and not shim ?

I've just brought one of these from streffords in worcester couldn't believe how light it feels for a 450. Nathen was so helpful with the sale think as it was dropped to them I brought it.

James you are a fantastic salesman sir!  That design on the radiator system re the extracting of evaporating coolant back into the radiators is a great detail, As a student of British military history, it was adapted by the the Desert Rats and the SAS on their vehicles for the same reason but the fact that GPX does that when most manufacturers do not even know about it, says a lot about the integrity of the guys behind the design.

These bikes are awesome 👍. GPX really great bikes.

Really wish we could get the 450 in the US.  GPX stopped selling them over here.

I will be purchasing in the new year James.

Looks brilliant how about a trail/ adventure version would sell by the boat load 👍

Amazing spec for a bike in this price range. It may be a little too much for a knackered 65 year old. I am certainly looking at the FSE 300.

Would be nice for you to film in Lanscape!

Yes looks a lovely machine with excellent service intervals. I would change the oil every 1000 miles minimum even more in dusty/Sandy conditions.
I do wonder why the handguards are not framed to the bar ends. But that's being picky on a really well priced bike. Really well priced.

Anyone fitted accessories (gps/heated grips) via a fuse box?  Is so, which fuse box and is it located?

Having owned a WR450F I'm split between the GPX300 and 450. It seems like the GPX has a more trail orientated engine than the Yam. Also I like the idea of the larger oil capacity. I also wonder if radiator guards are a good idea?

James you said its got a 1.8 litre fuel tank! That must be wrong!

i highly doubt zongshen makes engines for Yamaha YZs or WRs. maybe for scooters.

Am I imagining things, or does the 450 have longer service intervals than the air cooled 300?
