CRESCENT YAMAHA / PRO-BOLT: ULTIMATE TRACK DAY GYTR R1


Limited Edition "Ultimate Track Day" GYTR R1


Crescent Yamaha continues to expand its GYTR Pro Shop offering by launching its take on the ultimate track day R1, in the exclusive Jonathan Rea Winter Test livery by renowned motorsport designer Drudi Performance.


The team at Crescent aimed to create a track-only R1 that hits the sweet spot of peak performance, desirability and exclusivity, aligned with reliability and day-to-day usability, by specifying readily-available GYTR parts and additional Crescent performance tuning.

This exclusive Crescent Yamaha GYTR R1 is ready to hit the track with notable performance upgrades centred on practical, real rider demands. Beginning with the engine, Crescent Yamaha’s cylinder head porting and an increased compression ratio match the GYTR race kit camshafts, air funnel kit and factory-spec EWC Akrapovic exhaust to take this R1 to a power output of around 215bhp – a 30bhp+ increase over the standard bike. Performance and rideability are further enhanced via the fully-customisable GYTR kit electronics, via the race spec wiring harness and WSBK lookalike handlebar adjustment switches.


The R1’s grip and stability are amplified further by the WorldSBK style underslung swing arm and Ohlins TTX rear shock, alongside race-specification Öhlins road & track front forks with adjustable steering damper, as well as the complete industry-benchmark Brembo braking system and Marchesini forged-aluminium wheels.


This special bike is finished with the same care and attention to detail that you would expect from a WorldSBK-inspired Crescent Yamaha-built GYTR Pro Shop machine, including carbon bodywork, Pro-Bolt Titanium fasteners throughout, and further recognisable GYTR parts and one-off details.

There will be only 10 Limited Edition units built in the exclusive Jonathan Rea 2024 Winter Test livery colourway, all delivered with signed Crescent Yamaha certification and the opportunity to be a guest and meet “JR” at any round of the WorldSBK Championship. Every buyer who uses the bike on track will benefit from the support of a Crescent Yamaha GYTR Pro Shop technician by attending a track day of the customer’s choice to set up suspension, electronics and to ensure the bike is correctly adjusted to each individual client (UK track days only).

Paul Denning – Crescent Yamaha Managing Director and Yamaha WorldSBK Team Principal Paul Denning.

“We really wanted to ‘throw the kitchen sink’ at this Limited Edition “JR Winter Test” track bike, both from the GYTR catalogue and our other performance suppliers, to create the ultimate Crescent Yamaha track day R1 – and we’re pretty confident that we’ve nailed it! We want to cater to the guys who want something special but who also really want to use up their tyres and come back with a massive grin on their faces – and to do that we considered every part in terms of both performance and maintenance, with durability in mind. There are a lot of details on this machine that are super close to WorldSBK but still openly available in the market, so this bike is designed to be used. With the engine upgrades and torque output, we’ve created something that can make a mega lap time in skilled hands but still delivers the very forgiving, very linear power delivery that the R1 is famous for. Alongside a huge step in grip, braking power and stability, and coming in underneath the WorldSBK lower weight limit, this R1 is going to be very special to ride.”
