Yamaha SR250 "Type 4" by Auto Fabrica, via Bike Shed

Another SR, but this 250 conjures up mini trials bikes from Europe on the 70's and is detailed nicely (apart from the usual 'no front guard' criticisms, which I agree with - a white plastic mini VMX guard on the front would look perfect). Made by Auto Fabrica: http://www.autofabrica.com/#/type-4/
