Beta Xtrainer 300

please note i'm located in Hungary, and can't help with transportation!

bike has 48 hours currently,
at 31 hours main bearings, piston, and clutch plates were replaced.
at 40 hours front forks oil and dust seals, slide and guide bushings replaced,
at 45 hours, brand new original starter and bendix from beta were replaced, but it was an electronic fault so i include the previous starter and bendix which are working perfectly fine.
new battery, and ngk iridium spark plug.
new did xring chain, new brembo front brake pads.
bike has the airbox mod, rr pipe, and carb is jetted: 165 main, 38 pilot, n2zw needle.
pulls like an RR model.
new seat concepts confort seat which is 400 USD from USA + taxes.
nicecnc short clutch lever, clutch works like a dream.
tubliss in the rear tyre, moose in the front.
i include a lot of spare plastic, turn signals, mirrors, etc. but the bike can't be plated, no papers
I removed the dash at 31 hours and installed a separate hour meter.
oil tank and pump removed, so bike works with premix.
radiators have signs of hard enduro, but dont leak.
i find this bike too small for me, i'm 186cm, so i'd like a physically bigger bike( ktm exc 300, 350, or similar)
