I thought I would share this in case anyone was interested. I just finished fitting a 250 Ninja screen to the SWM for a bit better comfort on the highway. The screen was 20 bucks on ebay (new from China) and the brackets were made from scrap aluminium sheet. I've bodged up screens before and the key to stopping the plastic from cracking is to soft mount them with plastic or rubber between the screen and any metal fittings. The styling might not be to everyones tastes but for 20 bucks I reckon it's alright
Yesterday I went out for a blast and the wind was howling. Good news is the screen takes all the wind pressure off the chest. The air stream hits about chin height but is pretty smooth so no annoying head wobble. I'm happy enough to leave it how it is.
The standard tyres are OK in the dry but I reckon they would cake up with mud pretty quick with the narrow tread spacings. They move around a bit on the Perth ball bearing gravel but that just makes it more fun. Drop a foot down and slide it round!
