An ongoing problem with the engines was their propensity for surging or stalling with 68 incidents reported between 2003 and October 2016 though this rate had reduced after the introduction of the Block 3 engine version. The US Naval Air Systems Command intends to award Rolls Royce two contracts to examine the effectiveness of proposed reliability improvements, the first is a software tweak to the engine management software for the compressor guide vanes that internal testing showed could improve surge margin by % at sea level and 3% at altitude. The second is the discovery that a temperature sensor at the inlet of the compressor sends incorrect readings leading to % out of 4% steady power shortfall at the compressors correct rotational speed again correctable with a software fix. In addition Bell-Boeing are developing an inlet barrier system to reduce the power loss from the engine ingesting dust and sand particles to supplement the engines existing centrifugal based particle separators as they can only do so much to improve the quality of air they receive. 
The ZRX 1200 DAEG shown is beautiful. I am the owner of a 2002 ZRX1200R with 60,000 miles on the odometer and it will live in my garage into the unforseeable future. One thing that none of the other people who replied expressed is the versitality of these motorcycles. This is a bike that will do everything well. A friend asked me to participate as a monitor for the bike part of a triathlon. I looked over the bikes I have and decided that the ZRX would do well following these athletes at about 18 mph, and it did. It will carry passengers and/or camping gear with equal aplomb. If you need to wick it up to to 125 mph to pass a few cars in a short passing zone it will happily do that. I haven’t seen an adequate replacement.
LessorCare enables lessors to swiftly call upon Rolls-Royce maintenance and/or availability services, normally, but not exclusively, when the aircraft is between operators. Technical data and advice is available to lessors whenever they need it and a wide range of asset management services are available which help lessors to reap the maximum return from their engine investments. A key part of LessorCare is the creation of a dedicated aircraft transitions team within Rolls-Royce who use their market and engine knowledge to proactively and reactively assist with the smooth exit of aircraft from one operator and its placement and service entry with its next operator. LessorCare also helps lessors to maximise the terminal asset value of their engine inventory when they decide to finally withdraw them from service.
