If a motorhead says British Invasion or Sounds of the 60s, it's not about music, it could more likely be about a Triumph Bonneville T120R and how it sounds when you kick it to life. This is the quintessential British motorbike, the one the Japanese tried to recreate with the Kawasaki W650. Somehow it just became the bike we all picture as emblematic of the era.
The seller says:
There are no dents, dings or paint flaws in the sheet metal or tank. The period correct paint scheme and color is by Don Hutchinson in Massachusetts. Bike is a pristine original in all outward aspects down to the decals and emblems but has been improved for contemporary service as follows: new carbs (AMAL 389/203 which are correct for this year and model); new alternator (three phase for better charging at low speeds); new electronic ignition (Tri-Spark) in lieu of points and condensers (which come with the bike); new voltage regulator in lieu of the original rectifier (which comes with the bike); new screw-on air cleaners in lieu of the black, one piece canister (which comes with the bike); new brakes; new mufflers; new sealed wheel bearings; new tires per the original; 12-volt electrics in lieu of the old 6-volt components; new wiring harness per the original; new cables and new clutch discs.
Bike starts on first kick, despite not having a choke, if the carbs are properly bled. Has been run on Redline synthetic oil for the past two years and on high octane, leaded and ethanol free gas (LL100) - very good for the old engine. Unusual to Triumphs of this generation is not only matching frame and engine numbers, but also matching crankcase half numbers. The bike has had work done on the upper cylinders but not on the engine lower case or transmission which is all original and functioning perfectly.
If the seller's description is accurate, it sounds like all of the reliability issues have been taken care of. You get the look, the sound, the collectibility and the enjoyment of riding one of the best known of all of the British motorcycles. The photos seem to back up what he says, so it's probably worth a serious look though you may want to act quickly because it's for sale on eBay with a bid already close to the buy it now price.
