MY TLR250R Dyno Run - Carried out on Fuchs BEI 251 dyno 2nd May 2000. Rear wheel data below.
CO measured at 5% to 5.6% across rev range which co-relates to an
air/fuel ratio of 12.63 to 12.39 to 1, which is fine with 12 being about
ideal.
Revs P in HP and T in pounds ft
2.5 6 12.3
3 7.3 12.6
3.5 9 13.4
4 10.2 13
4.5 11.2 12.6
5 12 12.3
5.5 11.8 11.2
6 11.4 9.8
6.5 10 8
7 8 5.4
The figures indicates the nature of the beast with the torque curve flat for
virtually 3,000 RPM - all the way from just above tickover at 1,500 RPM.
The figures only start at 2,500 because it was tough to get a decent measurement
below that.
The power characteristics are all down to a long inlet, small carb, header
and soft cam etc, hence it doesnot breathe and rev out at higher RPM and
continue an upward path for torque/power. Mind you this graph certainly shows
useful power to the ground and consistent torque, so hence good traction which
together with a short wheelbase makes for much fun and an easy to ride motorcycle.
