A pair of race track specials

Aprilia and Yamaha have both launched a pair of track specials, each using technology derived from MotoGP and WSBK programmes.

Aprilia is on the rise in MotoGP, with both factory riders now vying for podium positions each race weekend. Aleix Espargaro has already won on the RS-GP at the Argentinian GP and Maverick Vinales achieved his first podium for Aprilia at the Dutch TT in Assen, followed by another at Misano last weekend.

Because 2022 also happens to be the 30th anniversary of Aprilia’s maiden Grand Prix title, the firm has released a commemorative RSV4 to mark the occasion, dubbed the XTrenta (trenta is Italian for 30).

Using the RSV4 Factory as the basis, it features new front aerodynamic appendages and rear winglets similar to those seen on the MotoGP bikes. There’s even a swingarm-mounted under-wing (“spoon”) fitted to decrease rear tyre temperature. The carbon fibre aero package evidently increases downforce by 25 percent, while also decreasing drag by four percent. 

Power gets a boost too, the 1100cc V4 outputting 230hp through a higher compression ratio and a titanium/carbon exhaust system. A full-titanium silencer will be a cost option. Superbike-derived water and oil coolers keep the V4 from overheating while a high flow air filter improves intake efficiency. 

The final engine upgrade is a Magneti Marelli control unit. Ohlins suspenders are used on the XTrenta, fettled by Aprilia MotoGP engineers. Tyres are Pirelli Diablo SBK slicks, while rims are forged magnesium Marchesini wheels for additional weight saving (overall 166kg dry).

Brakes comprise Brembo GP4-MS billet monobloc calipers and 330mm discs. There are also race footpegs, handlebar levers, and a CNC fuel cap. Finally, the livery harks back to paint used in 1992 in the 125cc MotoGP class.

Only 100 examples of the RSV4 XTrenta are being made and each unit will retail for €50,000 ($NZ81,500). Orders open today.

Meantime, Yamaha has also announced a track-only version of its R1, along with a host of performance parts developed by GYTR (Genuine Yamaha Technologies Racing) for its R1 sports bike.

A new R1 is due for release at some point, perhaps at EICMA, but in the interim the Iwata company has unveiled a track special called the R1 GYTR. It is named after the company that produces track bikes for racers to practice on, used by the likes of Miguel Olivera, Sam Lowes and Pedro Acosta. The company is also involved in WSBK and endurance racing.

The R1 GYTR is designed to make the special track offering more readily accessible. It just happened to launch around the same time as Aprilia’s RSV4 XTrenta track bike. 

Special kit on the R1 GYTR includes an Akrapovic exhaust, GYTR ECU and wiring harness, a PC interface cable, lightweight GYTR ABS control electronics, GYTR sprockets and race chain, BS R11 tires, and items like fuel cap, brake lines, calipers, brake pads, handlebars, race rear sets, screen and seat, all by GYTR.

The R1 GYTR is available through GYTR Pro Shops, 17 of which can be found in Europe. GYTR will also help with race set up for each customer.

Yamaha has also said that it will be launching the GYTR Pro range of parts to the public, offering more than 400 different components, all developed for WorldSBK machines. Supplies are evidently limited, however, as some are from outside suppliers like Akrapovic, Marelli, Ohlins and Brembo.

Yamaha says the full line-up of parts and sticker prices will be announced by the end of the year.
