The new thing in this version is the mix calculator. • A petrol and oil mix calculator. At the top you pick which of the three you want to know —the oil, the petrol or the ratio— and you set the other two with your finger; the missing one appears worked out, in large type. Petrol and oil each carry their own unit: litres, millilitres, US or imperial gallons and fluid ounces of both systems. The ratio is shown as a percentage and as 1:n at the same time, and one button leaves it set on the engine screen, which is where it feeds the calculation. The percentage is oil against petrol and not against the finished mix, which is how the classic charts give it: at 4 %, five litres of petrol take 200 ml of oil. And, in case you are coming from 1.0, what the previous version already brought: • Needle comparator. Pick two from the catalogue of 113 and both profiles are drawn on the same chart, with each needle's real dimensions: length, diameters, cone and biconical sections. • A database of 112 tracks with their altitude and the length of the layout. Choosing the track fills in the altitude, which is what really moves the jet. These are the altitudes of the track, not of the town, and it works with no signal. • Jetting logbook. It saves every session and afterwards you record what you actually fitted and how it went, separately for low, mid and high, with notes, laps and best time. Exports to CSV and can be backed up. • Share the setup as an image card, with the jetting and the conditions. • Type of oil in the mix: castor —mandatory in RMC 2026— or synthetic. • The Aprilia RS 125 now has its own reference model, anchored on its factory jetting. It used to fall back on the generic one, and the chart read lean on a correctly jetted bike. • 2026 RMC classes, with the EVO and MY20 specification stated explicitly instead of the engine year. • Fixed: text that appeared untranslated when sharing the app, the help screen that was unreadably small, and the «share» link, which pointed to a different app.

This version adds what you asked for the most and brings the app up to date with the 2026 RMC rules. • Needle comparator.
