I put a 42 tooth rear Thruxton sprocket on my 2018 T120 with the stock 17 tooth front sprocket. $43 from the Triumph dealer. Best $43 I ever spent. No issues with ABS, Speedometer, or Engine management. The stock 100 tooth chain now has adjustment room. The bike is very responsive without the jerkiness when leaving a stop. Mileage actually went up. The bike is fast now. Not a Thruxton R but much better than stock. Triumph should have put this on as original equipment. It's not the best combination for wear but a better match than the stock 16F and 42R of the Thruxton. Sixth gear is now usable. Tally Bally Ho.
