Mine weighs 356 kgs. But I do have an extra battery, reverse drive system, electrical gear change, adjustable and comfortable seats, extra fuel pumps and more extra's. I guess if you build it as light as possible you could go to about 300 kgs. Lighter wheel hubs are also available at RTR.

I didn't expect to get so many answers . Do you now how much the lighter RTR wheel hubs cost and what the weight saving is?
The RD lightweight hubs+uprights are now standard with the kit, they are roughly 4kg per side lighter. Hispec also make a far better quality but but more expensive option, this is what I use on my tR1ke.
The best weight saving is putting the driver on a firm diet....
Late 2010; Got interested, visited RTR & ordered a tR1ke February 2011; Purchased and dismantled a R1 April 2011; Started building June 2012; UK Approval by RTR July 2012; NL Approved and licensed! August 2012 and on: Driving & fine tuning.... August 2015; Sold my Tr1ke. Up for a new project.
