Hello I have owned YBR 250 from new I have to press covered around 27000 miles of trouble free biking I get around 90 miles to the gallon I have done some motorway travel when necessary and then travelled at seventy there is a bit more but I don´t think it would be wise to sustain the speed I think the paint work mainly on the wheels is a poor finish but I love it I don´t know how long it will last but I love it and would buy another in just over 5years I have had two rear tyres one new front and a new chain. It just feels like new I keep it clean and serviced every few months I´m not a tinker or spanner gal it´s reliable and suits me
