    Triumph Twin Power Bonneville 904s Special

    This 2008 Triumph Bonneville 904s EFI is a one off special built by the owner of TTP (Triumph Twin Power) as his personal bike with no expense spared. Due to age related rubbish eye sight and hearing, I have now stopped riding, so my pride and joy is now up for sale. The frame and the tank are more or less the only standard items left from the original bike.

    This bike was bought in 2012 with 8,000 miles on the clock and has now done 11,152 miles, only 2,500 miles since installing the 904s Big Bore Kit. The engine is producing 83.3bhp (+37.3% over OEM) with a juicy 64.4 ftlb of torque (+44.7% over OEM) and due to the lighter parts used, this bike weighs in at about 184Kg dry (roughly 10% less than stock & dyno graph to prove power & torque in photo's section).

    The available power with the overall lighter weight of the bike, along with the lighter alternator rotor gives brilliant acceleration and is great fun to ride.

    The suspension is customized. The GSX-R 750 inverted forks were completely stripped down with all bearings and seals replaced. They have been customized and tuned so they aren’t as harsh as a sports bike may need and give a superb comfortable ride, but also give the bike great fast road handling.

    This Bonnie has great acceleration, excellent top speed, handles beautifully and is extremely comfortable to ride. The fueling is obviously perfect, you won’t find a better example out there.

    The list of personalization and customization is extensive, so the list below is quite lengthy.
