2000 Triumph TT600 from United States of America
Summary:
A virtually perfect machine with modded ECU map, especially for its age and era
Faults:
The sprocket cushion dampers in the rear wheel hub dried out, shrank and caused jerky shifting. That problem was fixed by cutting up an old inner tube into sections that supplement the stock part and take up the slack.
I replaced the stock voltage regulator (preemptively) with a Shendengen.
A bicycle speedometer was installed and calibrated to display accurate speed.
A backlight failed in one of the instruments.
All else excepting consumables is original on this 21 year old motorcycle.
General Comments:
The knock on the 2000 TT600 was a horrible flat spot between 3000 and 4000 rpm and deservedly so. Thanks to the free TuneECU, a subsequently released and better Triumph map used as a starting point, and my refinement over 25 additional generations, my TT is the best running in the world with no flat spot and hard acceleration to redline. Mapping was never touched for RPM over 4250 and throttle over 50% - the upper sections of the Triumph mapping were always good. On fast street rides with liter bikes I'm rarely over 7000 rpm because of the TT's strong midrange.
I have several bikes including a Suzuki SV1000s and Triumph Trident 900. Of those, the TT requires the least shifting, accelerating smoothly from 20 MPH in 6th gear. It's light, comfortable for a sport bike with reasonably smooth engine and shifting. Build quality is absolutely on a par with any Japanese bike I've owned.
Would you buy another motorcycle from this manufacturer? Yes

A bit more on the TT600 EFI, it runs a non O2 sensor system, which the EFI measures engine load to set fuel/air ratio, hence the slight 'hunting'; later models use an 02 sensor to sniff exhaust content and set fuel. The TT also ran single butterflies per cyl, Daytona 600 ran dual butterflies, one for low revs and a 2nd for WOT; this tamed the engine at low RPM. The so called jerkiness at 2000 RPM is controlled by changing down a gear and running min 3500 RPM; remember the engine is designed for 8000 to 11,000 RPM track work, not as a commuter.
The clutch is fine but the trans likes fast shifts. I also found 15/50 full synthetic oil quietens the straight cut gears and clutch.
The bike needs a experienced rider to perfect its advantages which a novice would not. The bike is too good for novice riders.
