I am not really sure why people don't post much on here, I think it might due to a number of reasons
1) RTs are not that popular compared to GSs, far less of them around
2) a lot of RT owners do not do their own maintenance, the limit of most peoples "customising" is a bigger screen or different seat, hence there's not many discussions about maintenance
3) RTs generally are owned by older riders who aren't as "internet forum savvy"
The UKGSer forum is very busy, but the RT section on there is pretty dead
I try to post on here when I see items of interest on ebay, or I have some advice for anyone
