Most of the 750 F1's are road bikes weighing about 180kg, with a number of the special editions having alloy tanks (170kg ish) and higher-tune engines which go a bit better but are collectors items.
The TT2-replicas are based on race chassis from verlicchi and harris and weigh 140kg (ish) and there really arnt many around at all.
Mine is currrently not on the road as it wont run properly above 5000
and all my time is taken up sorting the proper race bikes
