The bearings are pre-lubed. Some info on the "ARS" bearing suffix is below and a photo of my spares.

Hi Norman, As far as I know the Mk1 and Mk2 bearings are the same but the crush drive/rear sprocket is different, the Mk2 does not have the rubbers. The last time my rear wheel bearings failed, the symptom was vibration from the seat and footboards at 50mph. The notchy bearing had caused the...

The right (battery) side fork leg removal requires the air intake to be moved up. Loosen the rear bolt and unclip the front rubber mount. I found a T45 x 200mm bit was needed to remove the lower pinch bolts due to the restricted space. See photos. The pinch bolts are fitted with Blue Loctite...

My 2017 GT got to 107mph on the GPS, 2 up, on a deserted Spanish motorway. Interestingly the speed did not increase on the slightly down hill section after the test. I do wonder if they are limited in some way.

Check the wheel bearings as a leaking oil seal is the first sign they are on the way out. The final drive rubbers were removed from 2016 on the MK2.

I recently removed my battery for 2 weeks when upgrading the forks, without issues with the windscreen. All I did was set the screen to the lowest positions before working on the bike.

MK2 has double barrel (shotgun) silencer. But to be safe look for the oil feed to the cam chain tensioner.

Leave the bike stationary for half an hour before starting the learn process. It is essential that only the sensor you wish to learn is active and its ID number is only visible in the MotoScan app after the learn process. The ID is not printed on the sensor case or packaging. Establish a...

The rear wheel bearings on my bike last around 12,000 miles, which I presumed was due to it regularly carrying two heavy people plus luggage. Recent facebook group posts have shown this not to be an isolated event, does anyone have any knowledge of the typical wheel bearing life or experienced...
