Mk1 Suzuki GSF1200 Bandit Streetfighter Custom
Welcome to the sale of a very special Bandit 1200. Probably one of the best on planet earth right now. Professionally built here at RCK. HPI clear.
The idea behind this bike, was to build a functionally updated, pure blooded MK1 Bandit 1200 . No chopping the back end off and putting silly seat units from other bikes on, no swapping out the forks for USD's that you dont need and dont fit the aesthetic. Front to back, just pure Bandit. We chose this bike because its honestly THE most powerful and crisp stock engine and gearbox ive ever sampled. The bike cried out to just be made better.
This was supposed to be a race bike. So function over form was the mantra whilst we were in the build process. Everything we upgraded has a purpose, we didnt care what it looked like, just that it worked and worked well. The key areas we wanted to address were the usual MK1 weak points. Sort the sloppy suspension, massively reduce the weight, address the 'from the factory' lean and choked running, whilst still maintaining a bike that can be ridden daily comfortably, but opened up on a track to scare some sports bikes. All in all after we were done, we managed to shave off a massive 42kg from the bike to bring it down to an athletic 180kg wet. A massive improvement. Roughly about an 8.8hp gain over stock just in weight savings. It now sounds like a WSBK, handles like its on rails, stops on a dime and pulls really strong, but still retains the classic bandit silhouette.
Below is a list of all the parts and prices on the bike. The numbers given are all the retail costs if you were to buy and build this yourself. So take this opportunity to get this bike at an absolute bargain. Remember, the prices below dont even factor in the labour cost to build a bike like this properly or the cost of the bike itself.

I have every receipt for every part on the bike so you can see its all legitimate and nothing cheap or Chinese has been used. The bike currently sits at 15,157 miles with full service history in the original service book. It has only turned about 6 miles from a few test runs since being built, to make sure everything is set right. It is essentially brand new.
