Review of castrol power1 racing oil(cp1r) on RC390.
I have done about 500kms on cp1r till date, and the experience is excellent and way above what i had expected. It did feel hot, usual 8 bars, but fan was running more than often in the initial 50-100kms but its all good now.The bike redlines smoothly and with a sense of urgency unmatched by 7100. City performance is good, and where the bike used to lug previously at specific gear/rpm combo on 7100, its going absolutely fine on cp1r.
On highways too, same thing, smooth acceleration and good fe. Ripping the throttle returns about 24-25ish on console, small improvement of 1-2kmpl on same stretch over 7100. Also happened to do a mini trackday, and it was good too. The exhaust pops are almost gone, and cooling/heating properties are similar as the 7100; 8 bars normally, 7 bars on early winter morning in mumbai . Overall, a good choice over 7100, and adds to the list of my minor mods having a substantial effect on behaviour of bike, viz Usage of Adon p, keiti traction pads, and gravity chain oiler.
Ps: Ensure you lay your hands on genuine castrol product, Ive heard many fakes are being circulated in market. I got it from navi mumbais castrol dealer.


the tire though is worth the extra moolah over the mrf's on my D200.
