MXA复古测试:我们乘坐JUSTIN BRAYTON的2010 JGR YAMAHA YZ450F

We get misty-eyed sometimes thinking about past bikes we loved, as well as ones that should remain forgotten.有时,我们会迷茫地思考着自己喜欢的过去的自行车,以及那些应该被遗忘的自行车。 We take you on a trip down memory lane with bike tests that got filed away and disregarded in the MXA archives.我们带您踏上记忆之旅,其中包括自行车测试,该测试已归档并且无视MXA档案。 We reminisce on a piece of moto history that has been resurrected.我们回想起一段已经复活的摩托车历史。 Here is our test of Justin Brayton's 2010 JGR YZ450F.这是我们对贾斯汀·布雷顿(Justin Brayton)的XNUMX JGR YZXNUMXF的测试。

The story of Justin Brayton's path to racing success is one that crazed mini parents should take note of.贾斯汀·布雷顿(Justin Brayton)迈向赛车成功之路的故事是一个疯狂的迷你父母应该注意的故事。 In fact, they should study Brayton's carefully selected career choices.实际上,他们应该研究Brayton精心挑选的职业选择。 Why?为什么? Justin Brayton isn't your typical modern-day professional.贾斯汀·布雷顿(Justin Brayton)不是您典型的现代专业人员。 While other aspiring professionals his age skipped out on school and spent their days riding for the sole purpose of establishing motocross dominance, Justin was hitting the books and going to public high school.他这个年龄的其他有抱负的专业人士跳出学校,花一天的时间骑自行车是为了确立越野摩托车的统治地位,而贾斯汀却在读书,上了公立高中。 Justin had a typical childhood, chock full of study halls, school dances and homecoming celebrations.贾斯汀度过了一个典型的童年,充满了自习室,学校舞蹈和返校庆典。 His parents stressed the importance of an education—a catalyst for his motivation to succeed regardless of the size of the task that lay before him.他的父母强调了接受教育的重要性,这是他取得成功的动力的催化剂,而不管摆在他面前的任务大小如何。 Like most sensible parents, the Braytons realized that their son shouldn't bet on turning Pro.像大多数明智的父母一样,布雷顿一家人意识到他们的儿子不应该赌转Pro。 Instead of putting all of his eggs in one basket, Justin earned his high-school diploma and had the opportunity to move on to college.贾斯汀没有把所有的鸡蛋都放在一个篮子里,而是获得了高中文凭,并有机会继续上大学。 For that, the为此, MXA 贾斯汀·布雷顿(Justin Brayton)对沉船工人印象深刻。

Of course, there are many other reasons we like Justin Brayton.当然,我们喜欢贾斯汀·布雷顿(Justin Brayton)的原因还有很多。 Justin had the misfortune of growing up in Iowa—an area that isn't exactly a hotbed for pro motocross racers.贾斯汀(Justin)在爱荷华州长大,这真是不幸的事。爱荷华州并不是一个适合越野摩托车比赛的温床。 Justin proved the naysayers wrong, however, and is now one of the premier racers in the world.贾斯汀证明反对者是错误的,现在已经成为世界上主要的赛车手之一。 He certainly stood up for Iowa.他当然支持爱荷华州。 

Justin rides with sheer intensity and never throws in the towel when the odds are against him.贾斯汀疾驰而至,在遇到不利因素时从不扔毛巾。 It also doesn't hurt that he's a friendly person with an intelligent perspective on racing.他是一个友善的人,对赛车具有敏锐的见识,这也没有什么坏处。 It's common knowledge that Brayton signed a two-year deal with the relatively new Joe Gibbs Racing team (JGR).众所周知,布雷顿与相对较新的乔·吉布斯赛车队(JGR)签订了为期两年的合同。 There are a few key bits of information that you need to know about the JGR team.您需要了解有关JGR团队的一些关键信息。 

(1) 该团队是著名足球教练兼NASCAR车队老板乔·吉布斯(Joe Gibbs)的小儿子科伊·吉布斯(Coy Gibbs)的创造力。 

(2) JGR于2008年派出了第一支越野摩托车车队(与车手Josh Hansen和Josh Summey一起)。 

(3) The race shop is located on the outskirts of North Carolina in what can best be described as NASCAR country.赛车场位于北卡罗来纳州的郊区,可以说是纳斯卡国家。 While Southern California is often labeled as the hot spot for the motocross industry, Huntersville, North Carolina, is NASCAR's nirvana.尽管南加州经常被称为越野摩托车行业的热点,但北卡罗来纳州的亨特斯维尔却是NASCAR的必杀技。 

(4) 科伊·吉布斯(Coy Gibbs)要求他的车队赛车手住在赛车场附近。 对于那些认为这不是一个可行选择的骑手,科伊要么继续前进到下一个可能的候选人,要么告诉他们“运气不好”。 吉布斯(Gibbs)的理由是,车队庞大的体育馆,训练设施,内部营养学家,医生和广阔的骑行场地为帮助骑手发挥最大潜能提供了最佳条件。 科伊是一个善良的人,但他希望获得投资回报。 他想确保他的车手投入时间和精力以取得最大的成功。 没有人能为此而责备他。

商谈:一件艺术品

JGR可以完全控制其自行车。 JGR仅使用他们认为可以达到最高性能的售后零件。 If JGR isn't satisfied with the choices, while innumerable, they take matters into their own hands and make the parts themselves.如果JGR对选择不满意,尽管选择不胜枚举,他们会自己处理问题并自己制造零件。 From drawings to CAD renderings to construction to testing, they oversee the specific part every step of the way.从工程图到CAD渲染再到施工再到测试,他们在整个过程的每个步骤都对特定零件进行监督。 Case in point, the team built its own triple clamps.举例来说,该团队建立了自己的三夹钳。 It was a painstaking task that soaked up a portion of the team's operational budget, but the result was a clamp that met their high demands.这项艰巨的任务占用了团队的部分运营预算,但结果却是满足了他们的高要求的解决方案。

Justin Brayton's Muscle Milk/Toyota/Joe Gibbs Racing/Yamaha YZ450F isn't remarkably close to a work of art;贾斯汀·布雷顿(Justin Brayton)的肌肉牛奶/丰田/乔·吉布斯赛车/雅马哈YZ450F并非一件艺术品。 it is, in fact, a work of art.实际上,它是一件艺术品。 Saying anything less about the bike would be like telling a swimsuit model that she has a decent figure.少说自行车,就好比告诉泳装模特她的身材不错。 As Jeremy Albrecht gave us a verbal walk-through of Brayton's bike, we couldn't help but give him an incredulous stare.杰里米·阿尔布雷希特(Jeremy Albrecht)口头介绍了布雷顿(Brayton)的自行车时,我们禁不住给了他一个难以置信的目光。 The attention to detail, the hours spent handcrafting parts, the mirror-like shiny frame, and the melding of aftermarket products with JGR-specific and factory Yamaha parts had our heads spinning like Linda Blair.对细节的关注,手工零件的制作时间,镜面光泽的镜架以及将售后产品与JGR专用零件和出厂的Yamaha零件融合在一起,使我们像Linda Blair一样动了脑筋。 It quickly became apparent that Brayton's YZXNUMXF was the product of a team's devotion to building the best bike possible.很快就发现,布雷顿(Brayton)的YZXNUMXF是团队致力于打造出最好的自行车的产物。    

JGR开发了自己的脚踏板支架盖(以防止泥土堆积在支架中),加压散热器系统(允许团队对散热器内部的压力进行增量改变),更宽更结实的叉形凸耳(以提高刚度),特殊的应答器支架(固定在顶部三重夹具上)以及排气中间部分和减震器之间的铝制隔热罩。 JGR可以避免暴露Filtron空气滤清器,因为Supercross履带很少积尘或泥泞。 It's also important to note that the team uses engine and suspension oil specifically developed and formulated by the JGR NASCAR team.还需要注意的是,该团队使用的是JGR NASCAR团队专门开发和配制的发动机机油和避震油。 Justin Brayton's mechanic, Patrick Barker, toils away on the frame, swingarm, kickstarter and rear brake arm to give these parts a mirror-like finish, while in-house engine specialist Dean Baker is in charge of the engine work on Brayton's and teammate Josh Grant's bikes.贾斯汀·布雷顿(Justin Brayton)的技工帕特里克·巴克(Patrick Barker)费力地在车架,后摇臂,反冲起动器和后制动臂上加油,以使这些零件具有镜面般的光洁度,而内部发动机专家迪恩·贝克(Dean Baker)负责布雷顿(Brayton)和队友乔什(Josh)的发动机工作格兰特的自行车。 

With respect to the suspension, Joe Gibbs Racing capitalizes on the technology and machines at their fingertips (thanks, in part, to the NASCAR team).关于悬挂,Joe Gibbs Racing利用了指尖上的技术和机器(部分要感谢NASCAR团队)。 The team's suspension guru, Jonny Oler, is a fan of Frankenstein creations.车队的悬挂大师乔尼·奥勒(Jonny Oler)是弗兰肯斯坦创作的粉丝。 The team uses Showa forks, even though the 2010 Yamaha YZ450F (just like in years past) comes stock with Kayaba units.即使49年的Yamaha YZ2.0F(与往年一样)都配备了Kayaba装置,车队仍使用Showa货叉。 Oler uses parts off various models of Showa forks to create what he calls “F-Type” units.奥勒使用昭和叉车各种型号的零件来制造他所谓的“ F型”部队。 The beefy XNUMXmm forks aren't available to the public, nor are they even accessible to factory riders.强大的XNUMX毫米前叉对公众不可用,甚至工厂骑手也无法使用。 Only JGR riders get the F-Type setup.只有JGR骑手才能获得F-Type设置。 The NT shock, labeled “Version XNUMX” by the team, contains a Renton titanium spring and is also very unique.由团队标记为“ XNUMX版”的NT减震器包含伦顿(Renton)钛制弹簧,而且非常独特。 

Being one of Yamaha's factory-backed teams has its advantages.成为雅马哈工厂支持的团队之一具有其优势。 JGR utilizes numerous parts that would be otherwise unobtainable, thanks to Yamaha's blessing.由于雅马哈的加持,JGR利用了许多原本无法获得的零件。 The works parts list includes a four-speed transmission (fifth gear is locked out), shock linkage arm, lightweight hubs, steel axles, a 280mm front rotor and brake hanger, gas tank heat shield and titanium bolts.零件清单包括四速变速箱(第五齿轮处于锁定状态),减震连杆臂,轻型轮毂,钢制车轴,XNUMX毫米前转子和制动器吊架,气罐隔热罩和钛螺栓。 

暂停由乔尼·奥勒(Jonny Oler)在内部完成。

LightSpeed用保护性碳纤维覆盖了链条导板,防滑板和前制动盖,以及钛制脚钉。 Strong Excel A18 rims are used, along with an RK chain, FMF Factory 60 titanium exhaust, Hammerhead holeshot device, JE Piston, Xceldyne valve train, VP Racing fuel, Carrillo Industries connecting rod and complete Hinson clutch.使用坚固的Excel A4.1轮辋,以及RK链,FMF Factory 997钛合金排气装置,锤头破口装置,JE活塞,Xceldyne气门机构,VP Racing燃油,Carrillo Industries连杆和完整的Hinson离合器。 Also on the parts list are a Renthal rear sprocket, 4 Twinwall handlebars, Renthal soft half-waffle grips, ARC levers, red CVXNUMX radiator hoses, Dunlop tires and N-Style graphics with a seat cover.零件清单上还包括Renthal后链轮,XNUMX Twinwall车把,Renthal软半华夫饼握把,ARC杆,红色CVXNUMX散热器软管,Dunlop轮胎和带座套的N型图形。 The team receives tremendous financial backing from Muscle Milk, Toyota and Sport Clips.该团队获得了Muscle Milk,Toyota和Sport Clips的巨大资金支持。

JGRMX在公司内部制造了大多数技巧部分。

测试骑行:放手

Justin Brayton's body size and shape epitomize the typical 450 professional racer.贾斯汀·布雷顿(Justin Brayton)的体型和身材是典型的170名职业赛车手的缩影。 He tips the scales at 5 pounds and stands 10-foot-XNUMX.他称体重秤为XNUMX磅,站立XNUMX英尺XNUMX英寸。 While he uses the standard footpeg height and subframe, his quirkiness resides in his lever position.当他使用标准的脚踏板高度和副车架时,他的古怪之处在于操纵杆位置。 What's funny is that有趣的是 MXA test riders didn't take issue with Brayton's lever position.测试车手对Brayton的操纵杆位置没有任何疑问。 Apparently, Justin is one of those riders who can notice a 1 millimeter rotation up or down from his go-to blade position.显然,贾斯汀是那些可以注意到从其刀刃位置上下旋转XNUMX毫米的车手之一。

虽然 MXA wrecking crew was aware that Brayton's bike had a special works four-speed transmission before they started testing, the JGR staff thought it pretty comical when one tester after another came in after riding and asked where fifth gear went.失事的船员意识到布雷顿的自行车在开始测试之前就具有特殊的四速变速箱,JGR的工作人员在骑车后一个接一个的测试人员走进来并询问第五档的位置时认为这很可笑。 In truth, every rider enjoyed the four-speed tranny, because second gear pulled further than standard.实际上,每个车手都喜欢四速变速器,因为第二档比标准档拉得更远。 The gear ratios allowed us to lug the engine or attack certain sections with the rpm range up and still move forward with ease.齿轮比使我们能够在较高的转速范围内挂上发动机或攻击某些部分,并且仍然可以轻松前进。 We'd be remiss to say that the four-speed was better than our previously favorite transmission—Tim Ferry's YZ426F three-speed tranny.我们不敢说四速比我们以前喜欢的变速箱Tim Ferry的YZXNUMXF三速变速器好。

JGR动力装置喷出了炽热的烈火,但仅在自行车挂上后才发生。 Compared to the explosive bottom-end power on the stock 2010 YZ450F, Brayton's JGR Yamaha was considerably more pleasant off the bottom but rocketed through the midrange and into the top end with alacrity.与股票XNUMX YZXNUMXF的爆炸性底端动力相比,布雷顿的JGR雅马哈从底端明显更令人愉悦,但却以中度的冲刺跃入中端并进入了高端。 

We are confident that Justin Brayton's JGR engine would be a significant improvement for any level rider.我们相信,贾斯汀·布雷顿(Justin Brayton)的JGR引擎对于任何水平的骑手来说都是一个重大改进。 That is the best compliment the那是最好的称赞 MXA 失事人员可以向任何赛车手支付引擎费用。 

JGR承认,自Supercross赛季开始以来,它已经朝着更柔和的方向发展。 If Brayton's results are any indication, the team went in the right direction.如果布雷顿的结果有任何迹象,那么该团队朝着正确的方向前进。

结论:我们真正想到什么?

There's a sense of accomplishment in testing a factory-level bike.在测试工厂级别的自行车时有一种成就感。 The的 MXA wrecking crew finds it difficult to turn down an opportunity to test unobtainable machinery.失事人员发现很难拒绝测试无法获得的机械的机会。 Every每一个 MXA Joe Gibbs Racing由完全相同的人组成。 JGR运用了令人难以置信的技术来提高其自行车的性能和工艺。 Justin Brayton's JGR Yamaha YZ450F is one of the trickest bikes we've ever tested.贾斯汀·布雷顿(Justin Brayton)的JGR Yamaha YZXNUMXF是我们测试过的最棘手的自行车之一。 That's saying a lot.说了很多。
