1983 Thunderbird Tiger Bonneville (Short stroke T140) For Sale
Owned one of these Thunderbirds brand new in 1981: so I know this one now definitely rides as it should, after carrying out necessary jobs. I have covered 4,000 trouble free miles since the engine refresh and upgrading work was carried out by ex-Triumph Co-op dealership mechanic. Absolutely everything works properly: neutral light, indicators, tachometer, speedometer, lights etc. Purchased this particular bike in May 2018 for my birthday since my original TR65 was stolen in the 1980s and I fancied another one. The bike is unmolested and has only covered 16,700 miles from new as evidenced by the provenance that I have collected. The bike was off the road for quite a while up until a few years ago. Have fitted Pazon electronic ignition, new carburetter, new original type silencers, new K70 tyres. Prior to my ownership of the bike the previous owner had done some work to it - new clutch and primary chain etc plus the front disc brake system had been overhauled. I have recently fitted another brand new K70 to the rear as I have enjoyed riding the bike and covered almost 4,000 trouble free miles in the last 2 years. K70 tyres are now made of a much softer compound so they have the grip as well as the original look but they don't last like they used to. These old style Triumph bikes are much lighter than modern day copies. These oil in frame bikes also handle very well. Bike is kick start only but a very easy starter. The Triumph TR65 650cc has a shorter stroke than a T140, runs smoother than a T140 and revs about 500rpm higher (71.5mm stroke and 76mm bore). The TR65 still has a good amount of torque and is an easy going ride, top gear mostly like a T140, given the very flexible motor. The bike is a bit more lively than a T140 and will rev high without any issues (roller bearing on timing side as standard from factory). The bike would stand a 43 tooth or 45 tooth rear sprocket for lower revs. A 45 tooth rear sprocket should result in a similar revs to speed ration as a T140. The bike is very well maintained by me and I have just serviced it, all oils changed and engine oil paper filter changed (have fitted the modern conversion sump plate). The rear grab rail has also been centralised by me. The back of the bike does not look uneven or twisted as is often the case. 12 months MOT just been obtained from the start of May. All of the original parts that were removed for upgrading have been kept. Bike has a side stand fitted and it has a rev counter fitted plus the central console as per the later T140s. Twin exhausts are fitted which look like factory originals together with the silencers that I removed due to serious inner corrosion. The twin pipes do make the bike sound much better than mine did back in 1981 with the black siamesed exhaust system. Are you are looking for a really well sorted British classic bike that is in ready to ride condition right from the word go? If so, then have a look at this bike. Basically a T140 Tiger which is a single carb T140 Bonneville, but the TR65 has a shorter stroke motor.
